On touch devices, .msg-actions is only shown on .chat-msg:hover, which may make the copy/redo actions effectively unreachable. Consider adding a @media (pointer: coarse) rule similar to .history-item-delete/.history-item-rename to keep .msg-actions visible (or provide an always-visible affordance) on coarse pointers.

Suggested change
/* Ensure message actions are visible on touch / coarse pointer devices */
@media (pointer: coarse) {
.msg-actions {
opacity: 1;
}
}
