   Every value reads an Almanac token from tokens.css. No hex
   literals, no new color, no new chart language (doc 25 §3/§7).
   Light + dark work automatically because all colors alias the
   theme-aware tokens.

   BOLD CHROME (doc 25 §11.5) — the top bar + left drawer are a bold,
   distinct chrome surface (dark chrome / light canvas, PowerBI-Aikido
   feel) so the working canvas pops. Every theme family defines its own
   chrome flavor in tokens.css + tokens.<family>.css; these rules consume
   only the chrome token set (--surface-chrome · --ink-on-chrome ·
   --ink-on-chrome-dim · --chrome-border · --chrome-hover · --chrome-active),
   never a hardcoded hex. Amber (--accent-primary) stays the single accent.

   Scoped under .bishell__topbar and .bi-rail so the canvas (and any
   floating LIGHT popovers that happen to live inside the chrome DOM —
   ops menu, palette chooser, locale menu) keep their own surfaces.
