/* V7-HEADER
 * Version:  v1.3.0
 * Issued:   2026-03-01
 * File:     mamadex-videos.css
 * Path:     assets/css/mamadex/partials/mamadex-videos.css
 * Author:   Buktika Command Team
 * Owner:    Buktika — Binka
 * Purpose:  Layout and styling for the MamaDEX explainer videos section.
 *           Section renders inside the canonical .sdx-card-section shell defined
 *           in global.css. This file owns only the internal layout: video grid,
 *           video-card structure, and thumbnail trigger area.
 *           All selectors scoped under .page-mamadex per V7.1 §4.2.
 * Type:     CSS stylesheet
 * License:  © Buktika, 2026. All rights reserved.
 * ISO Reference: ISO/IEC 15897, ISO 27001
 * Source Naming Standard: Buktika v7.1 (ISO Aligned)
 *
 * ChangeLog:
 *   v1.3.0 (2026-03-01): Design System v4.0.0 / Colour Map v3.8.0 compliance rewrite.
 *     REMOVED - .page-mamadex .mamadex-videos shell override block entirely.
 *               width: calc(100vw - 40px), max-width: none, border-radius: 28px,
 *               background: rgba(255,255,252,0.96), border, box-shadow all deleted.
 *               sdx-card-section in global.css owns the section shell. Page CSS
 *               MUST NOT redefine section geometry (Design System v4.0.0 §4.4).
 *     REMOVED - .mamadex-videos .videos-header position:static / z-index:auto block.
 *               Symptom-suppression for a sticky header that never existed in this
 *               context. Dead code. Deleted.
 *     REMOVED - .mamadex-videos .videos-header * transform:none block. Same reason.
 *     REMOVED - .mamadex-videos .videos-header .intro glass-pill treatment.
 *               backdrop-filter glass is restricted to lightbox captions on the dark
 *               overlay backdrop (Colour Map v3.8.0 §8.8.6). A glass pill on body copy
 *               inside a white card surface is an anti-pattern.
 *     FIXED   - .video-card background: rgba(255,252,244,0.96) → var(--card).
 *               Hard rule: no hardcoded hex/rgba for any tokenisable colour (§2.3).
 *     FIXED   - .video-card border: rgba(211,196,170,0.55) → var(--border).
 *               Same rule.
 *     FIXED   - .video-card-title font-size: 17px → 1.0625rem (Unit Standard §15.2).
 *     FIXED   - .video-card-copy .muted font-size: 16px → 1rem (Unit Standard §15.2).
 *     FIXED   - .mamadex-videos .videos-header h2 font-size clamp: px → rem
 *               (Unit Standard §15.2).
 *     FIXED   - All selectors now scoped under .page-mamadex (§4.2 scope rule).
 *     ADDED   - .video-card border-left: 4px solid var(--page-accent) — canonical
 *               card accent always at rest (Design System v4.0.0 §6).
 *     ADDED   - .video-card hover: translateY(-3px) + shadow only. No border change
 *               (Design System v4.0.0 §6 canonical hover rule).
 *   v1.2.1 (2026-02-23): V7.1 header compliance and muted fallback fix.
 *   v1.2.0 (2025-11-18): Original version.
