/* Directed Growth Systems.
   A shrine assembled from fragments: the loudness lives in the pictures, the
   text column stays a quiet place to read. Night first, violet, lilac-white
   glow. The taste is dgs/visual.md (rewritten 2026-10-19 around parafaith);
   web/design_rules.json is the machine copy and fails the build on a
   gradient outside .ambient, glow on body text, motion that reduced-motion
   does not cancel, a fifth family, a radius or an emoji.

   Every colour in this file lives in the generated block below. Everywhere
   else says var(--name), which is what stops a third colour entering without
   first entering web/design_tokens.json where it would need bounds. */

/* TOKENS:BEGIN v2 week 0 - generated by web/design.py from web/design_tokens.json.
   Do not edit by hand. `python3.11 web/design.py render` rewrites it,
   and `check` fails the build if it is stale. */
