/* ── Module caption ─────────────────────────────────────────
   One line, bottom-left, over whichever module is open. Built by
   landing.js on open; see the note there for why this exists
   instead of the .lf-hud panel below it.

   No panel, no border, no backdrop filter. A caption that needs a
   card to be legible is competing with the thing it captions —
   over a near-black module a text-shadow is enough to hold small
   mono type at any brightness underneath it. */
