/*
 * Detector Lab — internal fixture browser + timing dashboard.
 *
 * Neo-kinpaku tool shell. This is a genuinely page-specific app layout
 * (fixed sidebar + workspace + iframe + metrics), so it keeps its bespoke
 * structure rather than forcing the marketing kit's .ks-section grid onto it.
 * Every color, rule, and type value reads from kinpaku-tokens.css (--ks-*).
 * The fixture iframe renders untouched test HTML — only the lab chrome is themed.
