   HTML أو داخل innerHTML — أي حالة عرض/تخطيط ثابتة
   يجب أن تمرّ عبر كلاس هنا بدلاً من ذلك. التبديل
   الديناميكي عبر element.style.x من JS يبقى مسموحاً
   (لا يخضع لهذا القيد) ولا علاقة له بهذه الكلاسات.

/* No !important here on purpose: main.js toggles visibility for these same
   elements via element.style.display = '...' at runtime (a direct CSSOM
   property set, which CSP's style-src does NOT restrict, unlike the style=""
   attribute or setAttribute/cssText). A plain inline style always outranks a
   class selector in the cascade, so JS can still show/hide normally — adding
   !important here would freeze every one of these elements hidden forever. */
