/*!
 * My Dine — Shared Page Styles (v1)
 * File: /frontend/css/md-pages.v1.css
 * Purpose: Shared, reusable layout + typography primitives for frontend pages.
 *
 * Conventions:
 *  - Keep selectors prefixed with `md-` to avoid collisions with legacy CSS.
 *  - Pages compose these primitives and keep page-specific rules local.
 *  - Navbar height is injected via CSS var `--md-nav-h` (fallback 76px).
