/*
 * The console's appearance.
 *
 * This is an operator tool. It is SCANNED, not read: somebody submits a scenario, glances at nine
 * rows, and needs to know within a second which of them stopped something. So the design budget
 * goes to the reading order and to making a verdict legible at a glance, and nowhere else. There
 * is no illustration, no gradient for its own sake and no animation that carries no information.
 *
 * ── Severity is encoded in FORM, not only in colour ─────────────────────────
 *
 * Three states matter — something is blocked, something is waiting, something is clear — and each
 * gets a distinct SHAPE as well as a distinct hue:
 *
 *   blocked   a solid stripe running the full height of the row, and a square mark
 *   waiting   a hatched stripe, and a diamond mark
 *   clear     a short centred stripe, and a round mark
 *
 * Printed in greyscale, seen by somebody with deuteranopia, or rendered on a projector that has
 * eaten the reds, the three are still three. Colour is the fast channel; shape is the one that
 * cannot be lost.
 *
 * ── Semantic colour is separate from accent ─────────────────────────────────
 *
 * `--accent` is the product's own hue and is used for interactive chrome only: focus rings, the
 * primary button, links. The severity tokens are a different family and never borrow from it, so
 * changing the brand cannot change what "blocked" looks like, and an accent that happens to be red
 * cannot come to mean "stopped".
 *
 * ── Both themes, twice over ─────────────────────────────────────────────────
 *
 * `prefers-color-scheme` is the default signal. `:root[data-theme="dark"|"light"]` overrides it,
 * because the toggle in the header has to win in BOTH directions — a viewer in a dark OS asking
 * for light gets light.
