/* ============================================================
   HELIX — system styles
   Precision instrument. Hairlines everywhere; numbers prized.

   tt-web port (Phase 1 Commit 1, 2026-05-24):
   Global element resets (body, img, svg, a) scoped under .h-theme
   so they only fire on pages opted into the Helix design system.
   Box-sizing stays global — matches Bootstrap 4. html scroll-padding
   stays global — harmless. Component classes (.h-*) are unscoped:
   they only render when markup carries Helix classes.
