/* =============================================================================
   Pepvela Shop V3 -- foundation, global shell and shared components.

   Direction (CEO, 2026-09-30): a 2050 biotech commerce platform. Minimal,
   clean, futuristic, premium, scientific, straight to the point. Deep navy
   foundation, blue neural / molecular detail, soft violet and lavender
   accents, icy cyan highlights, lots of negative space, subtle glass and
   depth, restrained cinematic motion. Not a traditional store, not a SaaS
   landing page.

   Loaded after css/v3-tokens.css (spacing, radius, motion tokens) and
   css/v3-palette.css (the locked colors) on every V3 page, in place of the
   legacy css/shop.css. Colors come only from the palette; derived tones are
   alphas of palette colors.

   Type: Plus Jakarta Sans for everything, styled like the Stitch reference:
   compact and technical (display 48, section 32, card 18-22, body 14-16,
   11px uppercase microcopy, tabular figures for data). The Georgia serif is
   for the pepvela wordmark only (typography lock).

   The shell keeps every hook the storefront scripts and tests rely on:
   .util-bar / .util-mail, #navLinks, .nav-actions, .sf-cart-link /
   .sf-cart-count / .sf-cart-ico, #mobileNav, .shop-footer, .footer-signup,
   .footer-disclaimer. The cart drawer and notice (js/cart.js)
   get their V3 skin in section 10; the Research Access modal (js/age-gate.js)
   styles itself.
