/* ==========================================================================
   Pillbox product branch — shared styles
   Logic Foundry design substrate (cool-neutral v2 tokens + locked 5-face type,
   lifted from lf-prototype-v13) + product-page components.
   Product branch is deliberately CALM: no ambient particle field (per the
   PillBox website content spec — "stillness is on-brand"). Dark hero → light
   body theme journey and frosted glass are kept so it reads as the same site.
