/*
 * Landing page styles. No framework, no build step.
 * Scene: a tech lead at a small startup opens a link a teammate pasted into
 * chat, on a laptop next to three agent terminals, in the evening, deciding
 * whether this is worth a curl. Dark-first to sit next to those terminals and
 * to match the product; the light theme follows the system or the toggle.
 * Palette is the product's own: graphite ink, signal green for "live",
 * amber for "a human is needed", red for "stuck".
