/**
 * Sindesi — Base CSS (Fase 2.1 Tag D1, 16/07/2026).
 *
 * ## Ruolo
 *
 * Baseline CSS Sindesi proprietaria: normalize + typography + form + button
 * + layout + WP core support. Primo passo verso l'eliminazione di `style.css`
 * (3018 righe del framework hivetheme upstream).
 *
 * ## Strategia deploy (D1 → D3)
 *
 * **D1 (questo file, 16/07/2026)**: deploy accanto a `style.css`. Nessuna
 * rimozione. Test visivo in produzione — obiettivo zero regressioni. Se
 * `sindesi-base.css` copre correttamente uno stile, quello vince per
 * cascade (caricato dopo `style.css` via dep chain). Se manca qualcosa,
 * `style.css` fa da fallback silenzioso.
 *
 * **D2**: audit blog templates (`templates/post/*`, `comments.php`, ecc.).
 * Se `/news/`, `/karriere/` non esistono in WP → i template blog sono
 * dead → posts/tags/comments in `style.css` diventano rimuovibili.
 *
 * **D3**: rimozione `style.css` completa dopo verifica zero regressioni
 * in produzione. Tema perde 69KB CSS legacy.
 *
 * ## Cosa NON è qui
 *
 * - Selettori `.hp-*` HP forms/listings: vivono in `sindesi.css` finché HP
 *   Marketplace è attivo. Al distacco HP (Fase 3 strategica) → dead.
 * - Blog templates styling: rimandato a D2 dopo audit.
 * - Header/footer del sito: già Sindesi-native (post Tag A/B/C1/C2).
 * - Dashboard styling: vive in `sindesi-core` plugin (`assets/css/dashboard.css`).
 * - Icone: Phosphor self-hosted, separato.
 *
 * ## Design tokens
 *
 * Coerenti con `sindesi-core/assets/css/dashboard.css` — stesse variabili
 * `--sd-*` per allineamento cross-plugin.
