/* =============================================================================
   Pepvela main site V3 -- the longevity intelligence ecosystem (CEO, 2026-10-02).
   One stylesheet for every V3 page: semantic tokens (light + dark), type, the
   global shell (header, navigation, footer), components and motion.

   THEME: light and dark from day one. Components use ONLY the semantic tokens
   below (--bg, --surface, --text-primary, --accent ...), never raw colors, so a
   theme is just a token set. First visit follows prefers-color-scheme; a manual
   choice (the header toggle) is stored in localStorage "pv-theme" and applied
   by the inline script in every <head> BEFORE this file paints, so there is no
   flash of the wrong theme. Account sync is a later phase.

   Palette (CEO): navy #01021B #080327, indigo #1e1648, violet #5934CF #6c52e3,
   lavender #9B9AF0 #C2C3F4 #ede9ff, icy cyan #76BFE6, light surface #F8F9FC,
   light text #F6F7FF. Translucent forms of these only. No decorative orange.
   Type: Plus Jakarta Sans for everything; Georgia only for the pepvela wordmark.
   Motion: slow and calm; prefers-reduced-motion gets a complete still version.
