/**
 * Web-specific overrides for the unified reader.
 *
 * Loaded only on web pages using standard DOM (NOT in Chrome extension context).
 * These styles handle web-specific presentation like full-bleed backgrounds
 * and other visual treatments that don't apply to the extension overlay.
 *
 * ## Architecture: Context-Specific Overrides
 *
 * The unified reader uses a modular CSS architecture:
 * - **style.css** - Shared base styles (both contexts)
 * - **style-extension.css** - Extension-only overrides (Chrome extension Shadow DOM)
 * - **style-web.css** (this file) - Web-only overrides (standard DOM)
 *
 * ## Build Process
 *
 * This file is copied to backend/public/reader/ during the backend build:
 * 1. packages/backend/scripts/copy-unified-reader.js copies this file
 * 2. Outputs to: backend/public/reader/unified-reader-share.generated.css
 * 3. Web page HTML loads it via <link> tag after unified-reader.generated.css
 *
 * ## NOT Loaded By Extension
 *
 * Extension only loads:
 * - style.css (shared base)
 * - style-extension.css (extension overrides)
 *
 * Keep this file focused on web-only overrides. If a rule should apply to both
 * contexts, put it in style.css. If it's extension-specific, put it in style-extension.css.

/* ===== SHARE TRANSCRIPT (SSR) =====
 * The server renders a static transcript into #share-transcript so:
 * - crawlers index real text (no JS required)
 * - humans see content instantly while the reader bundle loads
 *
 * Without explicit styles, the browser briefly paints the transcript using
 * default UA styling (the "raw HTML" flash). These rules keep the transcript
 * presentable with minimal, dependency-free CSS.
