/* ABYLAY — the public story page and the signed-in workspace.
 *
 * Loaded after theme.css, so it inherits the token list and nothing here
 * hardcodes a colour. Every value goes through a token; that is what makes
 * dark mode a remap rather than a second stylesheet. If you add a colour and
 * dark mode grows a light patch, you hardcoded a hex.
 *
 * Two surfaces live here:
 *   1. #view-home  — what a visitor sees signed out. Description, not product.
 *   2. #view-panel — the workspace, reachable only signed in.
