/*
 * The agent panel, in webmcp.academy's own clothes.
 *
 * Light, on the marketing site's --bone, with its ink hairlines, offset hard
 * shadows and type. The palette and geometry are lifted token for token from
 * styles.css — matching it exactly is the point, so do not "tidy" these values
 * into something approximate.
 *
 * The vocabulary is the site's, applied to this panel's parts:
 *
 *   .card    -> a tool call      bone-lift, ink hairline, offset shadow
 *   .chip    -> a tool name      ink hairline, mono, muted
 *   .form    -> the composer     bone-in inputs, ink borders, mono caps labels
 *   .btn--fire -> send           accent fill, ink offset shadow
 *   .form__msg--ok -> the result line   lime fill, lime-ink text
 *
 * Lime is a *fill* here, never text. On a dark ground --accent2 is a signal
 * colour; on bone it is nearly invisible, which is why the site pairs it with
 * --lime-ink and why this file does too.
 *
 * Read tools carry a lime shadow, the one tool that acts carries the accent —
 * the light-ground equivalent of .toolcard and .toolcard--fire in the homepage's
 * chat mockup, which is a drawing of this exact panel.
 *
 * FONTS: needs Bricolage Grotesque and Chivo alongside JetBrains Mono. Every
 * demo's index.html must request all three. The fallback stacks below make
 * forgetting survivable rather than broken.
