/**
 * Thuy Bich Vinh Long — Brand Utility CSS
 * File: css/tb-brand-utilities.css
 *
 * Source:
 * - Split from remaining Yellow Pencil legacy in Phase 12F-D.
 *
 * Owner:
 * - Shared legacy brand utility classes used by UX Builder sections.
 * - .tb-eyebrow / .tb-heading / .tb-h1 / .tb-h2 / .tb-h3 / .tb-p / .tb-btn-* groups.
 *
 * Not owner:
 * - Header: css/tb-header.css.
 * - Footer: css/tb-footer.css.
 * - Blog Hub / Blog Single / Blog Archive.
 * - PLP / PDP / Product Card.
 * - Newsletter: intentionally removed.
 *
 * Notes:
 * - This phase is a split only, not a visual redesign.
 * - Values preserve the existing UX Builder look as much as possible.
 * - Future phase can align these tokens to tb-site-common after UAT.
