   page.css — light subpage layer for /hizmetler/<slug>/ (Stage 07).
   Loads AFTER tokens.css + base.css. NO sections.css on subpages:
   the few shared classes used here (nav, foot-*) are mirrored below
   so service pages stay light (no universe/GSAP, no bento machinery).
   Everything via var(--*); the ONLY literal product colors live inside
