 * Rules for future templates:
 * - Consume ip-* + existing zx-* / od-* chrome only
 * - No random paddings: use --ip-sec-y and gap tokens
 * - No duplicate button/card CSS per template
 * - First real page (condition) = content + composition only
 *
 * Namespace: ip-* (inner-page). Homepage visual CSS is untouched.
