/**
 * RSL Media Transcript Styles - Unified Pattern (Audio + Video)
 * Purpose: Calm, long-form reference reading for all transcript types
 * Reference: VIDEO_PROCESSING_SUMMARY_2026-01-06.md
 * Status: Production
 * Date: 2026-01-06
 *
 * Design Principles:
 * - 68ch line length for cognitive relief
 * - Preserved spoken cadence (no editing)
 * - Trust-preserving (no auto-scroll, no animation)
 * - Editorial consistency (same pattern everywhere)
 * - Accessibility-first (keyboard focus, screen reader friendly)

   What This Avoids (By Design)
   ========================================================= */

/* ❌ Summarization
 * ❌ Highlighting "key moments"
 * ❌ Pagination or "read more"
 * ❌ Interpretive framing inside the transcript
 * ❌ JS dependencies
 *
 * All restraint preserved.
