/* Exosphere Agentic - shared theme for the demo hub (Exos Systems).
 *
 * Served as /exos-theme.css from the hub root and linked by every demo surface; /nav.js injects it
 * if a page forgot. One file holds the whole look:
 *
 *   1. Tokens       light on :root (the default), dark on [data-theme="dark"] (set on <html>).
 *                   The toggle lives in /nav.js and stores 'dark' | 'light' under localStorage
 *                   'site-theme'. There is deliberately no prefers-color-scheme branch.
 *   2. Aliases      the variable names the existing page scripts and markup already use
 *                   (--panel, --ink, --gold, --accent, --line ...) mapped onto Exos tokens, so
 *                   markup generated by JavaScript we may not edit turns Exos-coloured too.
 *   3. Base         element defaults wrapped in :where() - zero specificity, so any page rule wins
 *                   regardless of stylesheet order.
 *   4. Components   namespaced .exos-* only (pages already use bare .card/.btn/.badge names).
 *   5. Chrome       the top bar, footer and theme toggle that /nav.js injects. Hardened with
 *                   two-class selectors so bare page rules (button{}, footer{}, a:hover{}) cannot
 *                   restyle it.
