/**
 * Premium Memberships extension for the phpBB Forum Software package.

 * Loaded automatically by templates that declare:
 *   <!-- INCLUDECSS mt_premium.css -->
 *
 * Templates consuming this file:
 *   - premium_body.html               Region selector
 *   - premium_argentina.html          MercadoPago plans grid
 *   - premium_international.html      PayPal plans grid
 *   - premium_return.html             Checkout result page
 *   - ucp_premium_memberships.html    UCP — user's membership panel
 *
 * Conventions:
 *   - All custom classes are prefixed `.mt-` to avoid collisions with phpBB native.
 *   - BEM-like naming: block / block__element / block--modifier.
 *   - Design tokens declared on :root (CSS custom properties).
 *   - phpBB native classes (.panel, .button1, .button2, .table1, .errorbox,
 *     .successbox, .notice, .details, .responsive-table, .rightside) are
 *     never overridden globally — only scoped composition.
