/*
 * Codigi QA Forum — Reddit-minimal, host-aware design system.
 * ───────────────────────────────────────────────────────────
 * The forum reads its palette and typography from the HOST THEME first (via the
 * WordPress block-theme preset custom properties `--wp--preset--*`) and only
 * falls back to neutral defaults when the theme exposes nothing. Every derived
 * surface/border/muted tone is computed from the resolved text/background with
 * color-mix(), so the forum auto-adapts to light OR dark host themes without any
 * per-site configuration ("generata in automatico e in linea col sito ospitante").
 *
 * Everything remains overridable via the `clc_qa_forum_custom_css` option
 * (loaded AFTER this file) or by redefining the tokens on `.clc-qa-forum`.
