// AutoEQSL drives automatic eQSL sending. The backend decides eligibility on
// log (auto-send on, recipient e-mail known, default template, not already
// sent) and emits "qsl:autosend"; this component does the part Go can't —
// render the card off-screen, rasterize it to JPEG and hand it back to
// SendEQSL. Jobs are processed one at a time. Mounted once, near the app root.
