/* ── Admin fields, unified ──
   `.form-group input/textarea` (shared with the storefront contact form,
   see line ~378) already sizes most admin fields, but a handful of raw
   inputs never picked up any class (variant option/spec rows, install/FAQ
   item rows, the generator's axis rows) and every <select> in the panel —
   including `.form-group select`, which the shared rule above doesn't
   cover — was falling back to the unstyled browser default. This block
   normalizes all of them to one bigger, cleaner, consistently-themed look
   and adds a shared focus ring, scoped to the admin panel only. */

/* ==========================================================================
   SMART PAGE — /smart. Reuses HOME V2 (hv2-*), ABOUT (about-cat-*, stat-card)
   and PRODUCT V2 (pv2-faq*) components as-is.

   The source design (the Lovable "Kerr Intelligent Spaces" page this is
   modelled on) deliberately alternates light and dark sections — only this
   page needs that; the rest of the storefront is intentionally all-dark
   (see the token block at the top of this file). `.smart-light` re-pins the
   same custom properties every reused hv2-, about- and pv2- component already
   reads (var(--text), var(--surface), var(--hairline), var(--gold)...) back
   to light values for its subtree — the same technique `.admin-wrapper`
   uses above to keep the admin panel light. Wrap a section in it and every
   component inside re-themes automatically; no per-component overrides.

/* ==========================================================================
   PREMIUM LIGHTING — /premium. A ported 1:1 design from an external
   reference build ("Kerr Lighting Brilliance"), not an original design here
   — copy, layout, spacing, colours (as oklch, matching the reference
   exactly) and motion are translated directly from that source, the same
   approach used for /smart-curtain-system above. "prm-" namespaced so
   nothing here leaks into the rest of the storefront; own colour tokens
   because the reference's palette is numerically different from this
   site's own black-and-gold tokens even though both read as "ink + gold".
   Headings/body intentionally stay on this site's own Instrument Serif /
   Inter (the reference uses Cormorant Garamond / Jost / JetBrains Mono) —
   the one deliberate non-exact value, matching the kcs precedent. Real Kerr
   nav/footer (via layouts/shop.php) replace the reference's own mockup
   header/footer. Reveal-on-scroll reuses the site-wide .anim/.in-view
   mechanism (see NAVBAR script in layouts/shop.php) instead of a page-local
   equivalent, since it already does exactly what the reference's React
   Reveal component does. Accordions use native <details>/<summary>, same
   technique as the SMART PAGE FAQ above. ========================

   ==========================================================================
   Ported 1:1 from an external reference build ("Lumina Architecture" / KERR
   Façade Lighting, built in Lovable). "fac-" namespaced so nothing leaks
   into the rest of the storefront. Token VALUES are copied from the /premium
   page's --prm-* set (renamed --fac-*) — the two dark premium marketing
   pages deliberately share one palette. Headings/body stay on this site's
   own Instrument Serif / Inter (the reference uses Archivo / Manrope), the
   same deliberate exception used on /premium and /smart-curtain-system.
   Real Kerr nav/footer (layouts/shop.php) replace the reference's own mock
   header/footer. Reveal-on-scroll reuses the site-wide .anim/.in-view
   mechanism wired in layouts/shop.php. FAQ uses native <details>/<summary>.
