   THE DESIGN ATLAS — engine chrome
   ────────────────────────────────────────────────────────────────────
   Reuses the page's own scale exactly (--s*, --step*, --ease*, --t*,
   --r*, --font-mono/serif) — one scale for the whole page, no drift.
   library.css owns the eight aesthetic directions and the component
   kit (--sp-*, .sp-*). This file owns everything the atlas needs on
   top of that: the cue system, the seven wing regions, the rail, the
   seams between regions, and the racks/wings/mixers/index that host
   the specimens.

/* ══════════════════════════════════════════════════════════
   1 · THE CUE SYSTEM
   ──────────────────────────────────────────────────────────
   A cue is a trigger (`.cue`) plus its text (`.cue__t`). The text is
   ALWAYS in the DOM, always exposed to assistive tech via the classic
   clip-based sr-only technique (never display:none/visibility:hidden,
   which most screen readers drop from aria-describedby) — so hiding a
   word here never removes it, only defers its visible form. Hover,
   focus and tap all trigger the same reveal. Native `popover` gives
   us light-dismiss, top-layer stacking and Esc-to-close for free where
   supported; the `.is-shown` class is the fallback path atlas.js drives
   everywhere else, so the mechanism degrades to "always works."
