 * OpenRiC shared shell, v1.
 * Canonical source: https://openric.org/assets/shell/v1.css
 *
 * WHY THIS EXISTS
 * OpenRiC is four independently deployed surfaces - openric.org, the reference
 * API at ric.theahg.co.za, viewer.openric.org and capture.openric.org. That
 * modularity is one of the project's strongest technical claims and is not
 * being given up. But a visitor should not have to reason about it, and until
 * now each surface had its own header, its own type stack and its own idea of
 * what colour a Place is.
 *
 * This file is the one place those decisions live. It is loaded cross-origin
 * by the other surfaces, so treat every change as a change to four live sites.
 *
 * DEGRADATION
 * Consuming pages keep their own base styling. If this file fails to load, a
 * page loses the shared chrome and falls back to its own look - it does not
 * break. Nothing here is required for a page to function.
 *
 * ENTITY COLOURS
 * The canonical set is the viewer's src/colours.js, which is the most
 * considered of the three that existed. Before v1 the Browse demo carried a
 * different palette under a comment claiming it matched the viewer; it did
 * not - Record was #3b82f6 against the viewer's #45b7d1, Activity #ef4444
 * against #6f42c1. Anything colouring a RiC entity should now read these
 * variables rather than restate the hex.
