/**
 * NodeBench MCP — Daily Brief Dashboard HTML
 *
 * Single inline HTML string, zero build step. Tailwind CDN, Inter font,
 * dark-mode-first design matching the v4 design system from html.ts.
 *
 * 3 views (tab-based):
 *   1. Brief — metrics, features, source summary
 *   2. Narrative Lanes — threads by phase, events, claims
 *   3. Ops — sync status, tool frequency, verification cycles
 *
 * Privacy mode (camera presence detection):
 *   - Opt-in via toggle in header
 *   - Pixel standard deviation → presence detection
 *   - No face detection, no identity, no image storage
 *   - Public mode: sanitize entity names, hide task results, hide mailbox
 *
 * Auto-refresh: 30s poll with hash-based diffing.
