/* =================================================================
 * NUMATEC v2 — Industrial / Precision Mechanical Engineering Theme
 *
 * Layer 1 of 3: design tokens, typography, layout primitives,
 * header/footer, breadcrumb, buttons, forms, utility helpers.
 *
 * Loaded AFTER the legacy CSS files so every rule wins by source
 * order; we never use !important unless an inline style fight is
 * unavoidable (Bootstrap selectors are mostly overridden by being
 * more specific or appearing later in cascade).
