Consolidated the theme-system docs into one code-derived canonical doc covering the token model, the apply path, overrides, and the v87-v99 satellite modules.
v100.0.22026-05-31
·Documented the 3-tier token model plus the flat runtime-tokens form the renderer consumes
·Captured the real apply path: AppShell writes ~25 --lw-* CSS custom properties; there is no central applyTheme function
·Documented OKLCH crossfade, the localStorage override layer, and satellites (defineTheme, lineage, hash, accessibility, palette)
