/* ── Two-state shop CTA ─────────────────────────────────────────
   Used by [data-home-shop-cta] wrappers on index.html and
   services.html (and any future landing page) to flip between a
   live "Browse herbs / Browse Shop" button and a "Coming Soon"
   placeholder when the admin has disabled the herb shop.

   .shop-disabled is set on <html> by each page's pre-paint inline
   <head> script (reads localStorage hm-shop-enabled === '0') so
   the swap happens BEFORE first paint — no flash. The runtime
   /public/features fetch in public-feature-flags.js applies the
   same swap once the live response lands, in case the cache was
   stale. Both branches are styled like buttons; only one is
   visible at a time.

   These rules live in landing-v4.css (not components.css) because
   landing-v4.css is the stylesheet shared by every public landing
   page; components.css is only loaded by index.html and the app
   shell. */
