/*
 * The apex "coming soon" page — standalone, no build step, no network.
 *
 * The palette, type scale and surface treatments below are COPIED from
 * `apps/web/src/app/marketing.css` (the Get Out and Jam brand applied to
 * Hemiola's public pages) so the placeholder and the real site read as one
 * product. Values carried over verbatim: the `--mk-*` custom properties in
 * both light and dark, `.mk-h1`/`.mk-h2`/`.mk-lead`/`.mk-eyebrow` type,
 * `.mk-hero`'s near-black `#0a0a15` ground and its two-radial violet/amber
 * glow, `.mk-grad`'s heading gradient, `.mk-logo`'s violet gradient tile,
 * `.mk-card`/`.mk-tile` surfaces and shadows, and `.mk-badge`.
 *
 * v2 composes those same values harder: a taller hero, an inline staff
 * motif drawn in SVG (no external asset), and two full-bleed dark bands so
 * the page alternates light/dark/light/dark rather than running as one
 * column of tiles. The two sections the product is actually sold on —
 * writing together and playing the notes in over MIDI — get the weight.
 *
 * v3 shrinks the pictures. The five frames were full-width figures stacked
 * down the page; they are now one horizontally scrollable strip of small
 * cards, each of which opens full size in a `:target` lightbox. That keeps
 * the page short without losing the detail the frames are there to show.
 *
 * Nothing here is a promise: the page describes only what the build already
 * does, and it collects nothing, so there is no form, no script, and no
 * request that leaves the visitor's machine. The lightbox is therefore CSS
 * only. The screenshots in `shots/` are copies of committed `docs/review`
 * gate frames, so they cannot drift ahead of the build either.

 *
 * What this cannot do without script, stated plainly rather than papered over:
 * Escape does not close the overlay, focus is not trapped inside it, and the
 * page behind it still scrolls. The mitigations are structural — each overlay
 * sits immediately after the thumbnail that opens it, so Tab lands on its
