/* ---------------------------------------------------------------------------
   1. TOKENS
   Status hues are chosen to stay separable under deuteranopia/protanopia:
   the "good" tone is a teal-leaning green and the "bad" tone a red with a
   distinctly lower lightness, and every status is *also* carried by a text
   label or glyph — colour is never the sole signal.

/* --- 5k. Inventory --------------------------------------------------------
   Two things in here are load-bearing rather than decorative.

   The `.fig-*` set is how a money figure Sentinel is NOT certain about looks:
   a value that cannot be stated gets the same visual weight as one that can,
   because shrinking "we cannot say" into a footnote is how a $0 ends up being
   read as good news. And `.conf-badge.is-derived` carries a dashed outline as
   well as a different word, so an inferred figure cannot be mistaken for a
   measured one across a room — which is the distance a demo is watched from.

   No colour here is hardcoded; every one comes from a token, so light, dark
   and the monochrome print sheet are one implementation.

   Every colour below is a token. Nothing here is hardcoded, so the light and

   The share page (`/s/:token`) is server-rendered HTML outside the SPA, so it
   links this same stylesheet — which is why the `.share-*` rules live here
   rather than in a second file that would drift.
