/* --------------------- ARROW (filled glyph) ---------------------
   Brand has TWO arrow forms. Both should be used by *referencing the

   1. → filled arrow — the canonical CTA / nav glyph. Always coral.
      Use the baked variants for img usage:
        <img src="assets/icons/arrow-coral.svg" class="bf-arrow">
        <img src="assets/icons/arrow-mist.svg"  class="bf-arrow">
        <img src="assets/icons/arrow-navy.svg"  class="bf-arrow">
      …or inline `assets/icons/arrow.svg` (fill="currentColor") when
      the parent's `color` should drive the tint.

   2. ↗ diagonal stroke arrow — reserved for hero / "explore" moments.
      Inline `assets/icons/arrow-diagonal.svg` (stroke-width 1.8,
      fill="none", currentColor).

   Never paste the raw `<path d="M …">` data inline. If you find
   yourself doing it, link the SVG instead. */
