/* ============================================================
   BYLDA — Pearl for the static pages.

   The homepage (web/) is the reference: warm pearl ground, ink for text and
   the one accent, black pill buttons, white hairline cards, Lexend
   throughout (Inter only for tabular data). This file loads after os.css and re-themes every
   interior page to match it, so os.css keeps its structure and class names
   but none of its dark look. Tokens mirror web/src/tokens.css.
