/* ============================================================
   components.css — Reusable building blocks
   Components: site-nav, site-footer, btn (primary / secondary / tertiary),
   chip, card-block (+ .is-forest / .is-lime), input, hero, section-head, glyph.
   card-block-metric + card-image-led were Direction-phase reserve patterns;
   their CSS was removed from v1 until a screen uses them. Concept is
   preserved in `02-design-direction/direction-A-green/preview.html`.
   footer-character (lime blob) removed 2026-06-03; the brief footer-mark
   chip that replaced it was also removed shortly after — it wasn't adding value.
