   conversation avec un +**, `onclick="E.commentBlock(idx)"` → tiroir de

+  Icône = tracé `message-square` (Feather) + `+` centré.
   Masqué sur mobile (2 breakpoints, comme le handle) et sur page verrouillée.
   - remplace l'ancien `.block-actions` de `renderBlock` : rendu en `opacity:0`
     **sans règle de survol** (jamais de classe `.visible`) → un `+` invisible
