/* HELION RIFT — UI stylesheet (owner: ui). Linked by index.html / sandbox.html (ui.js links it if missing).
   Visual language: ice-cyan primary, amber caution, red danger; thin 1–2 px lines, angled corner brackets,
   skewed panels, subtle glow, tabular numerals, eased 150–300 ms motion. All sizes scale with --hx-s (HUD) /
   --hx-m (menus), set by the UI on resize (× Settings → HUD scale). Text never drops below --hx-min (labels) /
   --hx-min-s (tiny tags): font-size: max(var(--hx-min), calc(Npx * var(--hx-s))). Prefix: hx-. The core boot
   overlay (.hr-boot) is restyled at the end of this file into the title's logo lockup, so loading hands over to
   the title without a second loader.
   Fonts: Saira / Saira Condensed from Google Fonts when online; offline the embedded 'HX Condensed' and
   'JetBrains Mono' (src/ui/fonts.js) and macOS faces (Avenir Next [Condensed], Menlo) take over. */

   core boot overlay (.hr-boot, owned by src/main.js) — restyled into the title screen's logo lockup (same

   fading loader (.hx-fromboot: no logo intro) the two overlap exactly. main.js markup is "Operation" +
   "HELION RIFT": the element texts are hidden and the lockup is drawn with pseudo-elements.
