chore: release v0.27.23

Filled, with a hairline white edge — the same trick the home marker
uses. A ring is an outline drawn over whatever is beneath it, and eight
pixels of one over the satellite imagery was barely visible, which is
the whole reason the layer exists to be looked at.

Its own colour, in its own key, beside the switch that turns the layer
on. Separate from the decode colour deliberately: that one exists
because the band palette disappears over some basemaps, and cyan over a
pale sea has exactly the same problem for exactly the same reason. One
control for both would have forced the two layers into a single colour,
which is the distinction it took a shape to draw in the first place.

The picker only appears while the layer is on, since it configures that
layer and nothing else, and it is a portable UI pref like the other map
colours, so it travels with data/.

+      "SteppIR: a Calibrate button, beside Retract. It drives every element to its end stop so the controller re-learns where zero is — the cure for an antenna that tunes to the wrong length after a power cut mid-move, after the elements were pushed by hand, or after a motor slipped. It takes minutes and the antenna is unusable until it finishes, so it asks first. Ultrabeam controllers have no such command and say so rather than pretending. Retracting the elements was already there and now explains itself: it is the storage position, and the next tune brings them back out on its own.",
+      "On the rotor dial, the beam no longer whips a full turn round the compass when the antenna crosses north. A rotator at 020° turned anticlockwise reports 020, 010, 000, 359, 358 … and the animation travelled from 20° to 359° the long way — a complete revolution on screen while the mast moved forty degrees the other way. The beam now follows an accumulated angle, so what is drawn is the way the antenna is actually turning. Both lobes of a bidirectional antenna are handled separately, since they cross north at different moments.",
+      "The rotor widget stops claiming the antenna is turning every time the wind moves it. A threshold alone could not tell the difference — a gust pushes a beam well past four degrees and back, and each excursion counted, so Stop lit and went out all evening on an antenna that had not turned. What separates a rotation from the weather is not how far the reading moves but which way: a rotor under power advances, gust after gust reverses. A step now counts only when the previous one went the same way, so movement is announced one poll later on a mast that takes half a minute to cross a pass, and never at all on a windy afternoon.",
+      "LilacSat-2 gets its FM transponder — 144.350 up, 437.200 down — and its proper name, LO-90. It was shipped with nothing but an APRS digipeater, because the transponder database marks that transponder inactive: it runs to an announced schedule rather than continuously, which from a database looks exactly like a dead one. The label says \"(scheduled)\" so nobody wonders why it is quiet. The generator now also lists the satellites it refused on that ground and kept nothing else for, so the next regeneration is not silent about them.",
+      "A frequency OpsLog got wrong can now be corrected on a station that already has the satellite file. Until now the file was copied out on the first run and was the operator's from then on, so a mistake we shipped — LilacSat-2 with no FM transponder — had become their data and could never be mended. The plan now adds what is missing, brings up to date what was never edited, and leaves alone what was: an entry you corrected by hand outranks anything shipped, and the log names the ones it stood down on. The first run after this cannot tell the two apart, so it takes the shipped plan and copies your file to satellites.json.bak first — after that your edits are recognised precisely and survive every release.",
+      "The per-band antennas are applied to the satellite slices at last. The map is keyed by the band name in capitals, the tracker looked its two bands up in lower case, and so it read no antenna at all out of a table the operator had filled in — a 70 cm downlink stayed on the 2 m transverter. The log now names the band and the antenna it resolved, so a setting never made can be told apart from a lookup that missed.",
+      "Tracking now shows where the satellite is beside where the antenna points: azimuth, elevation, distance and altitude, in the same strip as the two frequencies. The elevation goes dim below the horizon, so a bird still being followed on its way up cannot be read as workable.",
+      "The two satellite lists in the settings are sorted by name, numerically — AO-27, AO-91, AO-123. The left one came in the order the frequency file happens to be written and the right one in the order they were clicked, so finding one bird among sixteen meant reading all sixteen. A satellite renamed on getting its OSCAR number, as LILACSAT-2 became LO-90, is also recognised in a followed list that still holds the old name instead of being listed as having no elements.",
+      "The grid-square map filters by one mode, by band and by satellite. The FTx button is gone: it grouped FT8, FT4 and FT2 together, while the question the map answers is where a single mode has been heard. The named modes are read from the log itself, so each one is offered only if there is something behind it — and FT2 appears for whoever is already using it, with nothing to change here the day it becomes a registered mode. The band list is the station's own plus anything worked outside it, and the satellite list only appears once a square has been worked through a bird.",
+      "Saving the satellite settings now refreshes the Satellites tab. It read the followed list once when it was opened, so un-following a satellite left it in the pass table and in the dropdown until the tab was reopened — which looks exactly like a setting that failed to save. The lowest pass, the window and the locator are picked up the same way, and a satellite that is no longer followed hands the selection to the first one that is.",
+      "The FT map takes one colour for every decode, next to the basemap buttons. The band palette is calibrated against a plain map — 60m navy and 70cm olive all but vanish over the satellite imagery — and it is only useful to somebody watching several bands at once, which most operators are not. Leave it empty for the colour per band, as before. The legend then keeps the band names and drops the swatches, since which bands are up is still worth knowing.",
+      "\"Later\" on an update notice now asks for how long: 1, 4, 12 or 24 hours. It only hid the card before, and the check behind it runs every five minutes, so the same notice came back four times an hour all evening for a version already declined. The delay is recorded against that version, so a newer release is different news and appears at once — a deferral can never bury an update. The cross hides it for an hour, and opening About still answers whatever was deferred, because asking is asking.",
+      "Stop stays lit for the whole rotation instead of blinking. Keeping the wind out took a four-degree step, but four degrees is four seconds of travel on a real rotor, so between two of them nothing confirmed the mast was still turning and the button went dark and came back the whole way round. Getting in stays strict — two steps the same way, which weather never gives — while staying in now needs only continued progress in that direction: one degree the same way is not a gust when the rotor is already under power.",
+      "The frequency plan is checked against AMSAT's live FM and image lists. AO-123 gets the 67.0 Hz tone its uplink needs, SO-50 says in its label that 74.4 Hz arms the timer before 67.0 can key it, and eight SSTV satellites are added — HC1PX, RS18S, RS27S, RS38S, RS40S, RS57S, RS58S and RS83S — as receive-only entries, with SSTV downlinks added to SONATE-2 and QMR-KWT-2. Every FM bird's uplink, downlink and tone now agrees with the published table.",
+      "The FT map can now show who hears YOU. \"Who hears me\" draws, in dashed cyan, every station reporting your own transmissions to PSK Reporter, alongside the solid arcs of what you decode — the direction you cannot see from your own receiver, and on FT8 the one that says whether calling is worth the cycle. It costs almost nothing: your callsign goes in the topic's transmit level, so the broker sends nothing else, and it works with the band-opening watch switched off. Off until asked for, and each station appears once with its freshest report inside a fifteen-minute window.",
+      "\"Who hears me\" is marks alone, no arcs. With a few dozen receivers reporting, a line to each made a fan out of one square that buried the decode arcs beside it — and the lines said nothing, since every one of these paths starts in the same place. The mark is a hollow diamond, fading with age: shape rather than colour carries the difference, the decode dots being filled circles and the arcs having used fourteen colours already.",
+      "The FT map's controls stop covering it. The basemap buttons had crept over Leaflet's zoom control, so the minus button took clicks meant for Street, and the row had grown with the colour picker and the reverse layer until it reached the middle of a world map — covering the Atlantic to save a top-right corner that was empty the whole time. Basemaps stay on the left, clear of the zoom; the colour and \"Who hears me\" move to the right.",
+      "The who-hears-me diamonds are filled and take a colour of their own, chosen beside the switch that turns them on. Filled with a hairline white edge, the trick the home marker already uses: a ring is an outline drawn over whatever is beneath it, and eight pixels of it over the satellite imagery was barely there. The colour is separate from the decode one because a single control would have forced both layers into one colour — the very distinction it took a shape to make."

+      "SteppIR : un bouton Calibrer, à côté de Rétracter. Il amène chaque élément en butée pour que le contrôleur retrouve son zéro — le remède à une antenne qui s’accorde à la mauvaise longueur après une coupure en pleine course, après avoir poussé les éléments à la main, ou après un moteur qui a glissé. Cela prend plusieurs minutes et l’antenne est inutilisable jusqu’à la fin : une confirmation est donc demandée. Les contrôleurs Ultrabeam n’ont pas cette commande et le disent, au lieu de faire semblant. Rétracter les éléments existait déjà et s’explique maintenant : c’est la position de rangement, et le prochain accord les fait ressortir tout seuls.",
+      "Sur le cadran du rotor, le faisceau ne fait plus un tour complet de la boussole quand l’antenne franchit le nord. Un rotor à 020° tourné dans le sens antihoraire annonce 020, 010, 000, 359, 358… et l’animation allait de 20° à 359° par le chemin long — une révolution complète à l’écran pendant que le pylône bougeait de quarante degrés dans l’autre sens. Le faisceau suit désormais un angle cumulé : ce qui est dessiné est le mouvement réel de l’antenne. Les deux lobes d’une antenne bidirectionnelle sont traités séparément, puisqu’ils ne franchissent pas le nord au même moment.",
+      "Le widget rotor n’annonce plus une antenne en rotation chaque fois que le vent la bouge. Un simple seuil ne pouvait pas faire la différence — une rafale pousse une beam bien au-delà de quatre degrés puis la ramène, et chaque écart comptait : Stop s’allumait et s’éteignait toute la soirée sur une antenne qui n’avait pas tourné. Ce qui distingue une rotation de la météo n’est pas l’amplitude mais le sens : un rotor sous tension avance, une rafale revient. Un écart ne compte donc que si le précédent allait dans le même sens — la rotation est annoncée un relevé plus tard sur un pylône qui met trente secondes à traverser, et plus du tout par vent fort.",
+      "LilacSat-2 récupère son transpondeur FM — 144,350 en montée, 437,200 en descente — et son vrai nom, LO-90. Il était livré avec un simple digipeater APRS, parce que la base de transpondeurs marque ce transpondeur comme inactif : il fonctionne selon un calendrier annoncé plutôt qu’en continu, ce qui, vu d’une base de données, ressemble exactement à un transpondeur mort. Le libellé indique « (scheduled) » pour que personne ne se demande pourquoi il est muet. Le générateur liste désormais aussi les satellites qu’il a écartés pour cette raison sans rien garder d’autre, afin que la prochaine régénération ne les passe plus sous silence.",
+      "Une fréquence qu’OpsLog avait fausse peut désormais être corrigée sur une station qui possède déjà le fichier satellites. Jusqu’ici ce fichier était copié au premier lancement puis appartenait à l’opérateur, si bien qu’une erreur de notre part — LilacSat-2 sans transpondeur FM — devenait sa donnée et ne pouvait plus être réparée. Le plan ajoute maintenant ce qui manque, met à jour ce qui n’a jamais été modifié, et laisse intact ce qui l’a été : une entrée corrigée à la main prime sur tout ce qui est livré, et le journal nomme celles devant lesquelles il s’est effacé. Le premier lancement après ce changement ne peut pas distinguer les deux : il prend donc le plan livré et copie d’abord votre fichier en satellites.json.bak — ensuite vos modifications sont reconnues précisément et survivent à chaque version.",
+      "Les antennes par bande sont enfin appliquées aux slices satellite. La table est indexée par le nom de bande en majuscules, le suivi cherchait ses deux bandes en minuscules, et il ne lisait donc aucune antenne dans un tableau que l’opérateur avait rempli — une descente 70 cm restait sur le transverter 2 m. Le journal indique désormais la bande et l’antenne retenues, pour distinguer un réglage jamais fait d’une recherche qui a échoué.",
+      "Le suivi affiche désormais où est le satellite à côté de là où pointe l’antenne : azimut, élévation, distance et altitude, dans le même bandeau que les deux fréquences. L’élévation s’estompe sous l’horizon, pour qu’un satellite encore suivi avant son lever ne soit pas pris pour un satellite travaillable.",
+      "Les deux listes de satellites des réglages sont triées par nom, en tenant compte des nombres — AO-27, AO-91, AO-123. Celle de gauche suivait l’ordre du fichier de fréquences et celle de droite l’ordre des clics : retrouver un satellite parmi seize obligeait à lire les seize. Un satellite renommé lors de l’attribution de son numéro OSCAR, comme LILACSAT-2 devenu LO-90, est aussi reconnu dans une liste de suivis qui porte encore l’ancien nom, au lieu d’y apparaître sans éléments.",
+      "La carte des carrés locator se filtre par mode précis, par bande et par satellite. Le bouton FTx disparaît : il regroupait FT8, FT4 et FT2, alors que la question à laquelle répond cette carte est de savoir où un seul mode a été entendu. Les modes proposés sont lus dans le journal, donc chacun n’apparaît que s’il y a quelque chose derrière — et FT2 est proposé à qui l’utilise déjà, sans rien à changer ici le jour où il deviendra un mode officiel. La liste des bandes est celle de la station, complétée par ce qui a été travaillé en dehors, et la liste des satellites n’apparaît qu’une fois un carré travaillé par satellite.",
+      "Enregistrer les réglages satellite rafraîchit désormais l’onglet Satellites. Il lisait la liste des suivis une seule fois à son ouverture : retirer un satellite le laissait dans le tableau des passes et dans la liste déroulante jusqu’à la réouverture de l’onglet — ce qui ressemble exactement à un réglage qui ne s’est pas enregistré. L’élévation minimale, la fenêtre de prévision et le locator sont pris en compte de la même façon, et un satellite qui n’est plus suivi passe la sélection au premier qui l’est.",
+      "La carte FT accepte une couleur unique pour tous les décodages, à côté des boutons de fond de carte. La palette par bande est calibrée sur une carte claire — le bleu marine du 60 m et l’olive du 70 cm disparaissent presque sur l’imagerie satellite — et elle ne sert qu’à qui surveille plusieurs bandes à la fois, ce qui n’est pas le cas de la plupart. Laissez-la vide pour retrouver la couleur par bande. La légende conserve alors les noms de bandes et abandonne les pastilles, car savoir quelles bandes sont ouvertes reste utile.",
+      "« Plus tard » sur une notification de mise à jour demande désormais combien de temps : 1, 4, 12 ou 24 heures. Le bouton ne faisait que masquer la fenêtre, et la vérification derrière tourne toutes les cinq minutes : la même notification revenait quatre fois par heure toute la soirée pour une version déjà refusée. Le report est enregistré pour cette version précise, donc une version plus récente est une autre nouvelle et s’affiche immédiatement — un report ne peut jamais enterrer une mise à jour. La croix masque pendant une heure, et ouvrir « À propos » répond toujours, même sur une version reportée : demander, c’est demander.",
+      "Le bouton Stop reste allumé pendant toute la rotation au lieu de clignoter. Écarter le vent demandait un écart de quatre degrés, mais quatre degrés représentent quatre secondes de course sur un vrai rotor : entre deux d’entre eux, plus rien ne confirmait que le pylône tournait encore et le bouton s’éteignait puis se rallumait tout du long. L’entrée reste stricte — deux écarts dans le même sens, ce que la météo ne produit jamais — tandis que le maintien ne demande plus qu’une progression continue dans ce sens : un degré du même côté n’est pas une rafale quand le rotor est déjà sous tension.",
+      "Le plan de fréquences est vérifié contre les listes FM et image d’AMSAT. AO-123 reçoit le ton de 67,0 Hz qu’exige sa montée, SO-50 indique dans son libellé que 74,4 Hz arme le minuteur avant que 67,0 puisse l’ouvrir, et huit satellites SSTV sont ajoutés — HC1PX, RS18S, RS27S, RS38S, RS40S, RS57S, RS58S et RS83S — en réception seule, avec une descente SSTV ajoutée à SONATE-2 et QMR-KWT-2. La montée, la descente et le ton de chaque satellite FM correspondent désormais à la table publiée.",
+      "La carte FT peut désormais montrer qui VOUS entend. « Qui m’entend » trace en pointillés cyan chaque station qui rapporte vos propres émissions à PSK Reporter, à côté des arcs pleins de ce que vous décodez — la direction qu’on ne peut pas voir depuis son propre récepteur, et en FT8 celle qui dit si appeler vaut le cycle. Le coût est quasi nul : votre indicatif est placé dans le niveau émission du topic, donc le broker n’envoie rien d’autre, et cela fonctionne même avec la veille d’ouverture de bande éteinte. Éteint par défaut, et chaque station apparaît une fois avec son rapport le plus récent dans une fenêtre de quinze minutes.",
+      "« Qui m’entend » n’affiche plus que des marques, sans arcs. Avec quelques dizaines de récepteurs, un trait vers chacun formait un éventail depuis un seul carré qui enterrait les arcs de décodage voisins — et ces traits ne disaient rien, puisque tous ces chemins partent du même endroit. La marque est un losange creux qui s’estompe avec l’âge : c’est la forme, et non la couleur, qui porte la différence, les points de décodage étant des cercles pleins et les arcs utilisant déjà quatorze couleurs.",
+      "Les contrôles de la carte FT cessent de la recouvrir. Les boutons de fond de carte avaient débordé sur le zoom de Leaflet — le bouton moins prenait les clics destinés à Street — et la rangée s’était allongée avec le sélecteur de couleur et la couche inverse jusqu’à atteindre le milieu d’une carte du monde, masquant l’Atlantique pour épargner un coin haut-droit resté vide tout ce temps. Les fonds de carte restent à gauche, dégagés du zoom ; la couleur et « Qui m’entend » passent à droite.",
+      "Les losanges de « qui m’entend » sont pleins et prennent leur propre couleur, choisie à côté de l’interrupteur qui les allume. Pleins avec un liseré blanc d’un pixel, le procédé qu’utilise déjà le marqueur de la station : un cercle creux n’est qu’un contour tracé sur ce qui se trouve dessous, et huit pixels de contour sur l’imagerie satellite se voyaient à peine. La couleur est distincte de celle des décodages, car un seul réglage aurait forcé les deux couches dans une même couleur — précisément la distinction qu’il a fallu une forme pour établir."

+// The FT map draws what this station decodes, which is one direction of every
+// path on it. The reverse — which stations are reporting our own transmissions
+// — is the half an operator cannot see from their own receiver at all, and on
+// FT8 it is the half that decides whether calling is worth the cycle.
+//
+// It is the narrowest possible slice of the PSK Reporter feed. The v2 topic is
+//
+//	pskr/filter/v2/<band>/<mode>/<tx call>/<rx call>/<tx grid>/<rx grid>/…
+//
+// so putting the operator's callsign in the TX level makes the broker send
+// nothing else. That is the whole reason this is cheap: internal/pskr measured
+// 83 messages a second for four bands unfiltered, and 0.2 to 1.2 a second once
+// filtered on the receiver's square — one callsign in the transmit level is a
+// handful of messages per FT8 cycle, however open the band is.
+//
+// Its own connection, like internal/pskrtgt has its own: the three want
+// different slices of the feed, and none of them can be filtered out of
+// another's. It also means this works with the band-opening watch switched off,
+// which matters — tying it to that feed's lifecycle would have made it fail
+// silently for anyone not chasing openings.
+//
+// Nothing is persisted. A report older than the window is dropped on the next
+// read, and an empty window means nobody has reported us recently, which is the
