/* index.html, the homepage — "the intelligence layer for coding agents".
 *
 * Designed in Telemetry (charcoal panels, hairlines, mono labels, bracketed eyebrows, one signal colour:
 * --tm-accent*, the visitor's Telemetry colour pick, amber by default) and drawn by this file in all five
 * visitor themes, like the Air Router page (air-router.css):
 *   Telemetry  html[data-final="telemetry"]                  the base tokens below
 *   Night      html:not([data-theme="studio"])               the live Final Dark look
 *   Day        html[data-theme="studio"] (data-final="light") the live Final Light look
 *   Cloud      html[data-final="cloud"]                      the soft app-store light (cloud.css)
 *   Cloud Dark html[data-final="cloud"][data-cloud="dark"]   Cloud on a charcoal ground (cloud-dark.css)
 * The palettes are tokens; the theme blocks at the end change the few shapes that differ (eyebrows,
 * buttons, headline accents, corners, shadows). Everything this file draws is marked data-st-own, so
 * studio-icons.js and the theme layers' generic rules leave it alone. Every rule is scoped under .th;
 * home-tm.js runs the demos. The hero's cost-saving visual is the old homepage's (.airllm-hero-viz, its
 * own <style id="hero-viz-style"> + hero-viz.js), painted by the shared theme layers as it was there. */
