 * Industrial skeuomorphic variants
 *
 * Opt-in dark industrial aesthetic for buttons and cards. Buttons feel like
 * physical spring-loaded keys; cards feel like raised bolted hardware modules.
 * These variants are MUTUALLY EXCLUSIVE with the regular .t3d-btn--primary /
 * .t3d-btn--ghost / .t3d-card--accent variants — pick one or the other on a
 * given element. Tokens live in tokens.css under "Industrial skeuomorphic".
 *
 * Usage:
 *
 *   Buttons:
 *     <button class="t3d-btn t3d-btn--ind-primary">PRIMARY CTA</button>
 *     <button class="t3d-btn t3d-btn--ind-secondary">Secondary</button>
 *     <a href="#" class="t3d-btn t3d-btn--ind-ghost">Navigate</a>
 *
 *   Cards:
 *     <div class="t3d-card t3d-card--ind t3d-card--hover">…</div>
 *     <a class="t3d-card t3d-card--ind-elevated">…</a>
 *
 *   Decorations (drop in as children of any t3d-card--ind* card):
 *     <span class="t3d-ind-screws" aria-hidden="true"></span>
 *     <span class="t3d-ind-vents"  aria-hidden="true">
