/**
 * Site-Specific Custom Styles (Layer 5)
 * =====================================
 *
 * This is the 5th and final layer in the CSS cascade:
 *
 * 1. main.css           → Platform base (header, footer, buttons)
 * 2. base-structure.css → Page layout (grids, sections, cards)
 * 3. tokens.css         → Design tokens (colors, spacing, typography)
 * 4. skin.css           → Theme skin (gradients, shadows, effects)
 * 5. site.css           → Site-specific customization (THIS FILE)
 *
 * THIS FILE HAS TWO SECTIONS:
 * ────────────────────────────────────────────────────────────
 *
 * Section A:  LAYOUT VARIANT CSS
 *   Loaded from design-system/layouts/<layout>/site-layout.css
 *   during cloning (Phase 5). Defines homepage grid, category page,
 *   and SEO component structures unique to each layout type.
 *
 *   Available layouts:
 *   - grid-cards   : Equal-height square product cards (default)
 *   - magazine     : Editorial 3-col with featured cards
 *   - masonry      : Pinterest-style CSS columns
 *   - list-rows    : Full-width horizontal rows
 *   - sidebar-nav  : 2-column split with sticky sidebar
 *
 *   The layout is set in site-profile.json → design.layout
 *   and auto-applied by generate-design-tokens.py during cloning.
 *
 * Section B:  CONTENT-TYPE-SPECIFIC STYLES
 *   Manually added per site for puzzle/content rendering.
 *   Examples: sudoku grids, arithmetic layouts, bingo cards.
 *
 * GUIDELINES:
 * -----------
 * DO:
 *    - Keep layout CSS in Section A (auto-generated)
 *    - Add content-specific layouts in Section B
 *    - Override generic styles for your site's unique needs
 *
 * DON'T:
 *    - Redefine design tokens (use tokens.css)
 *    - Copy/paste from other sites (each site is unique)
 *    - Modify Section A manually (re-run pipeline instead)
