 * Nivoli Games front end.
 *
 * Hand-written, no build step, no framework, no external font and no request to
 * anything but this file. Loaded only on the plugin's own templates (see
 * Template\Assets), so the rest of the site is untouched.
 *
 * Everything below is scoped under `.ng`, the wrapper each template opens with.
 * The one exception is the fixed reading-progress bar, which cannot live inside
 * a scrolled container, and the two `html.ng-js` hooks the script sets.
 *
 * The custom properties are the whole design system. Retune the six at the top
 * and the rest follows: every colour, rule, panel and shadow is derived from
 * them with color-mix, and each derivation ships a flat hex fallback first for
 * browsers without it.
