/* coding-tools.html — the Coding Tools page (since 2026-10-19; the page it replaced is in backup/): keep your coding
 * agent, let Air Router optimize the cost.
 *
 * One idea drawn throughout: your agent → Air Router → the best-fit model, with the request in the signal colour
 * and the response coming back in green. 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, with the same tokens as the Platform page (platform-page.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 <main> is marked data-st-own, so studio-icons.js and the theme layers' generic rules leave it alone. Every rule
 * is scoped under .ct; coding-tools-page.js draws the hero's wires and runs the demos (without it, every diagram
 * shows its finished state). */
