/*
 * Scaffold Template — template.css
 * ─────────────────────────────────────────────────────────────────────────────
 * This stylesheet is intentionally bare-bones.
 * It provides structure and layout plumbing only — no decorative colours,
 * no shadows, no rounded corners, no animations beyond a transition hook.
 *
 * All CSS custom properties are set per-instance by the PHP template via an
 * inline <style> block so they can vary per shortcode.
 *
 * CUSTOM PROPERTIES (set per instance in pztp-containers-menu.php):
 *   --sc-accent        Primary highlight / selection colour
 *   --sc-bg            Builder background
 *   --sc-text          Main text colour
 *   --sc-border        Border / divider colour
 *   --sc-font          Font family stack
 *   --sc-font-size     Root font size (applied to .sc-root)
 *   --sc-card-radius   Card corner rounding
 *   --sc-thumb-size    Item thumbnail width/height
 *   --sc-grid-cols     Card grid column template
 *   --sc-anim-speed    Transition duration
 *
 * HOW TO CUSTOMISE:
 *   1. Duplicate this file, rename it, and register the new name via the
 *      'pizzalayer_scaffold_partial' filter or by overriding pztp-template-css.php.
 *   2. Or enqueue a child-theme stylesheet that targets .sc-root and its children.
 *   3. Or use the "Custom CSS" field in the Scaffold template settings box.
