/* Helix functional / account-area component kit.
   Loaded only when is_blue() (alongside tokens/system/pages/shim).
   Source: redesign static mockups (_account-side.html, coupons.html,
   change-password.html). Pure .a-*/.d-*/.f-* selectors built on
   tokens.css vars — no body/element resets, safe to load globally. */
