/* ============================================================
   FABLE5 — HERO ("The Molten Core" forge hero)
   Visual layer for templates/fable5/partials/hero.php.
   ------------------------------------------------------------
   Scope: every rule is namespaced under .fbl-hero so it cannot
   leak into other sections (Phase 2 is hero-only).
   Palette: fable5-LOCAL component variables (--fbl-*), declared
   on .fbl-hero. These intentionally do NOT redefine global
   --mt-* tokens (that is the later dark-foundation phase) and
   do NOT reuse home_test token names. Layout primitives
   (radius / z-index) reuse existing --mt-* tokens.
