   CANONICAL CTA BUTTON SYSTEM
   ───────────────────────────────────────────────────────────────
   Use these classes for ANY new CTA. Color rule:

   .btn-primary       Green pill on white/cream backgrounds.
                      The default for every positive action site-wide.

   .btn-on-red        Gold pill for use on burgundy/sunrise/red backgrounds
                      (homepage hero, webinar hero, accelerator hero).
                      Green clashes with red, gold reads cleanly.

   .btn-on-dark       White outline pill for use on dark photographic
                      backgrounds (e.g. dark hero overlays). Inverts on hover.

   .btn-ghost         Green-outlined pill on white. Secondary action.

   All four share the .btn-base look (44px min height, 12px 26px padding,
   nowrap, focus-visible ring). Compose: <a class="btn-base btn-primary">
