/**
 * PepperLabz — Main CTA animation + hover/press states.
 *
 * SITEWIDE by design: every selector below is confirmed (2026-09-25, live
 * fetch) to have zero real matches on either homepage (page 95 or 9443) —
 * these buttons live only on product, cart and builder templates.
 *
 * REMOVED 2026-09-25 — .plz-bottom-btn, .pepper-verify-cta,
 * .pepper-info-btn: all three DO render on both homepages (they're part of
 * sections 3-6, which still share classes between page 95 and 9443 — that
 * independence rebuild hasn't happened yet). Enqueueing this file sitewide
 * with those three still in it was leaking their hover effects onto the
 * live homepage, the same failure mode as pepperlabz-hero-chrome.css. They
 * are not re-added anywhere for now — that's follow-up work once sections
 * 3-6 get the same treatment as the hero/promise rebuild
 * (pepperlabz-preview-home.css). See git history for the removed rules
 * (keyframes plzCtaChromeDrift / plzCtaEdgeGlow, and sections 3-4 of the
 * old header comment) if they need to be restored under new, independent
 * classes at that point.
 *
 * Two animations remain, chosen by surface type rather than applied
 * uniformly:
 *
 *   Dark pill buttons  -> continuous liquid-chrome sheen, accelerating on
 *                         hover. This is the motion language the hero
 *                         button already established, so the primary
 *                         actions read as one system.
 *     .plz-add-cart-btn, .checkout-button, .plz-sticky-add-btn
 *
 *   Light buttons      -> silver sheen instead of white, which would have
 *                         no contrast on a white face.
 *     .plz-builder-add-btn
 *
 * Palette is brand chrome only: #FFFFFF paper, #F1F3F5 mist, #C4CAD1 silver,
 * #79818A steel, #1C1F23 graphite.
 *
 * NOTE ON !important: several of these buttons are styled with !important in
 * additional-css.css, so overriding their declarations requires it here too.
 *
 * NOTE ON PSEUDO-ELEMENTS: every sheen layer is position:absolute, which
 * takes it out of flow. This matters because several of these buttons are
 * display:flex — an in-flow ::after would become a flex item and shift the
 * label.
 *
 * SEAMLESS LOOP: each sheen layer is 300% wide with a gradient tiled at
 * 33.3333%, and translates by exactly one tile per cycle, so the loop point
 * is identical to the start. Same technique as the hero.
