   storefront.css — STOREFRONT DESIGN SYSTEM · FOUNDATION  (Round 1)
   ---------------------------------------------------------------------
   Source of truth: dev_template/Storefront System Design Round 1
   ("One structure, three skins"). Every block reads ONLY the custom
   properties below; switching the Component Theme (data-ct) swaps the
   values — markup and class names never change.

       CT 1 — SOUQ     warm marketplace: pill buttons, big badges, dense
       CT 2 — ATELIER  editorial: serif display, square corners, 3:4 imagery
       CT 3 — KIOSK    bold + fast: 2px borders, offset shadows, 56px targets
       CT 4 — ES BASE  alias of Souq (kept so older Theme rows still render)

   FILES (loaded in this order by start-page.html / render.php):
       storefront.css   this file — tokens, reboot, containers, primitives
       sf-pages.css     functional pages not redesigned yet (cart, checkout,
                        account, product detail, order, info, quick order)
       sf-chrome.css    announcement bar, header, mega menu, search overlay,
                        mobile menu, mini-cart drawer, toast, footer
       sf-blocks.css    hero, USP strip, category tiles, promo, banner,
                        testimonials, brands, newsletter, countdown, CTA
       sf-catalog.css   product card variants, grid, carousel, toolbar,
                        filters, load more, skeleton / empty / error states

   CASCADE RULE (do not break): the CT sets sit at specificity 0,0,0
   (:where). view/storefront/render.php emits the merchant's Theme row as
   `:root, .sf-scope[data-ct]{--color-*}` AFTER this stylesheet at 0,2,0, so
   a store's own colours and body font always win over the CT defaults.
   Never raise a CT colour selector above 0,0,0.

   Every selector is scoped under .sf-scope so nothing leaks into the panel.
   Logical properties only (margin-inline, inset-inline-start…) — Arabic
   (RTL) is a first-class citizen, not a mirror afterthought.
