MediaWiki:Common.js: differenze tra le versioni

Versione attuale delle 19:58, 9 giu 2026

/* ============================================================
 * Common.js v7 — Wiki Methode Paret
 * ============================================================
 * REGOLA UNICA:
 *   URL /Titolo       → UI italiana
 *   URL /Titolo/ru    → UI russa
 *
 * Mobile detection v7:
 *   - Touch capability (funziona anche con "Versione Desktop" del browser)
 *   - Viewport width <= 1200 (più tollerante: cattura anche desktop mode 1080)
 *   - Una delle due basta
 * ============================================================ */
