/* Umma site. Persimmon brand (brief 013, docs/brand/README.md).
   Layout: a warm Flesh page; one persimmon moment per screen (the hero disc, the CTA pill),
   Leaf for anything that reads as text-in-colour, Seed for words.
   Contrast rules: Persimmon is a fill only, never text. Labels on Persimmon are Seed.
   Deep persimmon (#B04A12) carries icons and small accents on light backgrounds. */
