/*
 * YouTube Niche Scout — dark research surface.
 *
 * Design tokens are adapted from the Bolt "niche-scout-src" reference:
 * neutral near-black surfaces, hairline borders, a single restrained green
 * accent, dense research-oriented layout, compact cards and tabular numbers.
 *
 * Server-rendered only: no framework, no build step. The mobile navigation is a
 * checkbox disclosure driven by a cheap `transform: translateX()` (no layout
 * animation, no blur); the Mini App layer (bottom of this file) only adapts the
 * same pages to the Telegram WebView.
 *
 * Priority order for this surface: speed → usability → clarity → density →
 * aesthetics. No decorative gradients, no giant headers, no nested card towers.
