/* ── SPA container — elastic stage with a 1440×900 MINIMUM ────────────────
 * The app always fills the window exactly (width & height both, zero
 * letterbox bars, on any monitor) while never letting the LAYOUT get more
 * cramped than a 1440×900 design. index.html's inline script computes
 * `--app-w`/`--app-h`/`--app-scale` as: scale = min(1, vw/1440, vh/900);
 * appW = vw/scale; appH = vh/scale. Because width×scale and height×scale
 * both equal the real viewport size BY CONSTRUCTION, the stage always
 * exactly fills the window on both axes — there is no aspect-ratio
 * mismatch that could leave a bar. Whichever axis is tighter relative to
 * its floor renders at EXACTLY 1440 (or 900); the other axis comes out
 * LARGER than its floor (extra breathing room for the flexible middle
 * columns) instead of ever showing an empty margin. On a screen at or
 * above 1440×900, scale caps at 1 and appW/appH just become vw/vh — the
 * stage IS the window, natively, no scaling at all.
 *
 * `container-type: inline-size` makes #app the query container for every
 * page CSS file's `@container (max-width: …)` block (they were `@media`
 * queries before the landscape-lock — see the 2026-09-11 memory note).
 * appW is ALWAYS >= 1440 by the same construction above, so none of those
 * `max-width < 1440` blocks ever fire → the desktop layout is the only
 * layout, on every device size. The transform already makes #app a
 * containing block + stacking context, so `container-type` adds no new
 * side effects for the fixed-position overlays pages append into #app.
