/* Yellowbox case-study shell · Magazine Rail · v23 (Sep 26, 2026)
   v23: hardening pass from the Sep 26 systems audit, no new features.
   - Content-missing indicator (CASESTUDY-MISSING-01, new section at the bottom): styles for the
     small, muted, dashed-outline "⚠ missing: <field>" marker rail-shell.js's new `missing()`
     helper appends when a required CMS field/block is empty or absent.
   - Static runtime-injected CSS folded in (CASESTUDY-CSS-FOLD-01, new sections at the bottom):
     the v31 photo-loop, v28 credits-columns, and v30 gate-prompt styles used to be built and
     injected at runtime via `style#ybr-*-css` in rail-shell.js (v32 and earlier). They were
     static — identical byte-for-byte on every page load — so they're now here instead, and the
     matching JS injection code (and its call sites) has been removed as of rail-shell-v33.js.
     No visual change on any page.
   v21 (Sep 14, 2026)
   v21: N-option vote engine — text-option cards (info-grid strategy vote) and a "Shipped" reveal
   badge in the tally, shared with the existing image-option vote (boards). Vote option grid goes
   auto-fit instead of a fixed two columns, so 2 image options and 4+ text options both lay out
   correctly; unchanged for the 2-option case already live elsewhere. CASESTUDY-LEAGUE-VOTE-N-01.
   v20: Strategy option grid (name · tagline · rationale, winner badged) for info-grid blocks whose
   Strategy Options field is filled. CASESTUDY-STRATEGY-01.
   v19: On this page chips stick just under the real site header (--ybr-hh, measured live in JS) instead of at top:0, which was letting the header render over the chip row on phone/tablet.
   v18: mobile card/room interleave — .ybr-rail / .ybr-main go display:contents under 992px so their children share one grid and can be reordered with `order` (set in JS) instead of the whole rail stacking before the rooms.
   v17: gallery lightbox — dark full-screen viewer for any .ybr-gal / .ybr-pair image, arrows + counter + caption, X/Esc/backdrop to close.
   v16: vote option cards align bottom labels.
   v15: Pick a direction block.
   v14: On this page chips, phone and tablet only.
   v13: See it live card: illo beside label + host.
   v12: button anchors never underline; live-card fine print in full ink.
   v11: See it live card (green, Hello World illo).
   v10: board card.
   v9: branded lightbox (yellow header, UFO float + beam, lift-off on success); Start card on yellow with illo 53.
   v8: rail cards box-sized so buttons and inputs never overflow the rail.
   v7: full rail cards (quote, start, share, Made) + the lightbox (bottom sheet on phones).
   v6: type cards show specimens + alphabets in the brand faces.
   v5: body links in ink with a highlight underline · body after a gallery gets breathing room · rail link cards (Keep reading / From the market).
   v3: strip tiles show the whole thumbnail (square box, contain) instead of a 16:10 crop.
   v2: on tablet and phone the hero shows the key image at native ratio (no crop); desktop keeps the hand-chosen cover crop.
   Rules: no block crops the work; galleries are justified rows at native ratio; pairs share a height.
   Colours: YBX palette only. Canvas #FAFAFA · ink #191718 · lilac #CDB3FF · yellow #FBD305 · aqua #72F7E4 · green #86FF83 · pink #FF9FE2 · orange #FF8048 · subtle #F2F2F2. */
