/* ============================================================
   WULING UK — REUSABLE SECTION TEMPLATES: SHARED BASE
   ============================================================
   Loaded once, globally, before every other css/sections-*.css file.
   Defines the conventions every section partial in partials/sections/
   is built against, so all ~35 templates in the Section Library read
   as one consistent system rather than 35 one-off designs.

   CONTAINER / SPACING CONVENTION
   -------------------------------
   Every section: full-bleed background (colour alternates per section
   for rhythm — see .sec-alt below), inner content capped at 1400px
   (matches nav.css's own max-width), same horizontal gutter/breakpoint
   scale as the pillar sub-nav (56 / 40 / 32 / 24px) so a section never
   feels narrower or wider than the nav strip above it.

   Vertical rhythm uses a single scale: --sec-pad-y (96px desktop, tapering
   down at each breakpoint). Sections butt up against each other with a
   1px --border rule, exactly like the spacer blocks in the original
   bingo/index.php nav-preview page — so replacing a spacer with a real
   section changes only what's inside it, not the page's overall rhythm.

   IMAGE PLACEHOLDER CONVENTION
   -------------------------------
   No real photography/video exists yet for any vehicle. Every section
   that needs one uses .img-placeholder instead of a broken <img> tag —
   a fixed-ratio box with a visible caption naming exactly what asset
   belongs there, so Jon can see the intended layout AND know exactly
   what to shoot/source, without a missing-image icon reading as a bug.
   Usage:
     <div class="img-placeholder" style="--ratio: 16/10;">
         <span>Hero — Bingo, 3/4 front, studio</span>
     </div>

   2026-09-03: Jon asked for every section template to render as a plain
   single-sentence placeholder — not a designed layout — so the page
   structure is visible without pre-empting how each section actually gets
   designed later, one at a time. This is the shared look every
   partials/sections/*.php file now uses for its output. Matches the plain
   spacer-block style from the original bingo/index.php nav preview.
   Nav and footer are NOT part of this — they're already signed off. */
