/* GRAIN names, not the spine's --sol-* ones, and the reason is the ENTRY POINT.
   This file is compiled by vite into dist/index.css and folded into the CDN
   bundle dist/grain.css, which deliberately ships WITHOUT the compat layer
   (build-grain-css.mjs LAYERS; check-alias-inert.mjs asserts it). The night
   re-point of every --sol-* name lives in that layer, so a --sol-* value here
   would render daylight under [data-theme="dark"] on the CDN entry point.
   --background-sunken IS var(--sol-ground-sunken) in the light register
   (cream.css) and is re-pointed for night by dark.css, so it carries the
   compat layer's mapping on BOTH entry points. Components are different: they
   ship as class strings in dist/index.js and are compiled by the CONSUMER
   against the barrel, which does import compat. */
