/* ============================================================
   harrys.monster shared theme for the tool subdomains.
   Flat light version of the main site's halftone retheme (2026-09-21):
   system fonts, off-white page, white hairline cards, indigo accent,
   floating pill nav. No photo, no glass, no motion beyond hover.
   The same file is copied into every tool site; edit them together.
