 * contact.css — Polyphase Contact LP styles (Step 5)
 *
 * Reference: site-spec v0.4 §4.7, mock-contact-jp.html (v0.3 mock).
 * Scope rule: every selector is namespaced under `.page--contact` so it
 * cannot collide with other pages. tokens.css + base.css load first;
 * this file is loaded only on /contact/.
 *
 * Mode: Quiet Light throughout (no Mode D hero on Contact LP).
 * Color literals: none — only tokens.css vars (grep --signal / --rule).
 * Mobile breakpoint: 720px / 900px (matches mock).
