/* BooCode Classic — effects layer. Faithful revival of /opt/boolab
   data-mode='boocode' terminal-HUD chrome.

   Scoping contract (immutable):
   - EVERY rule is scoped under `.theme-boocode-classic` so the other 22 themes
     are byte-for-byte unaffected.
   - EVERY continuous keyframe animation is *additionally* scoped under
     `html.bc-anim-on.theme-boocode-classic`. ThemeFx sets `bc-anim-on` only
     when the Animated-background toggle is ON *and* prefers-reduced-motion is
     not set — so toggling either off removes the class and freezes all motion.
     @keyframes names are global (CSS can't scope the at-rule itself); they are
     `bc-`-prefixed and only *referenced* under the gated selector, so no
     animation runs unless the gate is on.

   The matrix-rain canvas lives in components/fx/MatrixRain.tsx (mounted by
   ThemeFx). This sheet adds: an Orbitron display wordmark + blinking caret, an
   app-wide scanline sweep, orange card hover glow + lift, terminal-frame chrome
   on the rails, and the ported boolab `.bc-*` / `.boocode-*` design-system
   classes (dormant until a HUD component consumes them). */
