/* Bedrock console — the authoring half of the product.
 *
 * Light ground, per the brand guidelines: "A light ground carries the whole
 * system — no dark surfaces." The viewer stays dark because a 3D scene of rock
 * needs to be, but the console is a working tool read for hours at a time and
 * takes the paper side of the brand.
 *
 * Three faces, matching the marketing site so the two halves are recognisably
 * one product: Space Grotesk sets headings, Inter sets prose, JetBrains Mono
 * sets every label and every number. Numbers are tabular everywhere — this is a
 * tool for people who compare tonnages down a column.
 *
 * Two colours differ from the console design file, both to clear WCAG AA on a
 * light ground, and both following the brand guidelines' own instruction that
 * accent-coloured *text* takes Accent 700 rather than Accent:
 *   --accent (#0088b0) is 3.7:1 on the page — fills, borders and rules only.
 *   --accent-700 (#006786) is 5.7:1 — anything accent-coloured that is read.
 *   --good was darkened from #1a8a5c (3.5:1 on its own chip) to #146c49 (5.7:1),
 *   because it carries the 10px LOADED tag, which is body text at tag size.
 * --ink-mute is likewise a step darker than the design's #8d9490 (2.8:1), which
 * would have put every column header, breadcrumb and stat caption below the
 * threshold. #8d9490 survives as --ink-faint for rules and the drag glyph, which
 * are not read. */
