/* ========================================================================== Customer sites — shared foundation (v2, 2026-09-06) Five fictional trade shops, five distinct structures, one contract. How theming works ----------------- • Each site sets its own default look on : data-trade, data-scheme="light|dark", and (optionally) --cs-* overrides in its own site.css. • The Demo kit "Looks" panel (css-pro/theme-presets.js) writes --pro-* variables plus data-layout / data-surface-mode on . Section 2 maps those onto the --cs-* tokens, so any palette flows through every site without per-site rules. • Layout variants from the Looks panel (data-layout) are handled as a few structural knobs in section 9. Each site's *default* structure is its own; layouts only nudge. Hooks other scripts rely on (do not rename) ------------------------------------------- .cs-topbar .cs-nav .cs-nav-toggle (motion-ui.js mobile nav + scroll state) .ms-reveal / .ms-reveal-stagger (motion-ui.js scroll reveals) form.cs-form #cs-request-form #cs-form-status .cs-shop-handoff (request-form.js) #request #cs-chat-root .cs-chat-* (deep-link.js, chat-embed.js) .cs-btn .cs-btn--primary .cs-btn--ghost .cs-sticky ========================================================================== */ /* ---------- 1.
