   Cor Portal v2 - mechanism detail ("The Lit Cue") component styles.
   Builds on tokens.css. Signature device: offset HARD double-shadow
   (teal close, gold farther), diamond rules, italic oxblood headings.
   Direction synthesized from a 3-way design exploration: Proto-C's constant
   lamp + draining seal, Proto-A's vertical-descent gravity + radiogroup a11y,
   Proto-B's color-death at ZERO. Honesty fixes applied (no invented numbers
   surfaced as data; cue held constant; qualitative state words + verdict only).
