Bug: Conversations low-severity defects (stale 'N selected' count after narrowing search; hardcoded blue with no dark variant)

[yannickmonney]

Area / route
Two confirmed low-severity conversations-inbox defects. Grouped; itemized below.

Sites

• [82] Narrowing conversation search keeps a stale "N selected" count and bulk actions silently mutate now-hidden rows
  • Evidence: use-conversation-selection.ts:70-89 (selectedCount=selectedIds.size, hasSelectedItems requires conversations.length>0); use-bulk-actions.ts:19-26 getSelectedConversationIds returns full selectedIds; conversations.tsx:251-355 bulk bar shown when hasSelectedItems
• [81] Active read-filter chip and bulk Send button use hardcoded bg-blue-100/text-blue-500 with no dark variant
  • Evidence: conversations.tsx:204 'bg-blue-100'; conversations.tsx:265 'bg-blue-100 text-blue-500 hover:bg-blue-200 hover:text-blue-600'; contrast automations/utils/step-icons.tsx:142 which includes dark: variants

Notes
[82] derive the action id-list and displayed count from the intersection of selectedIds with filteredConversations (or prune selectedIds on filter change) so bulk actions don't silently mutate out-of-view rows. [81] add dark: variants (or a semantic token) to the read-filter chip and bulk Send button, matching step-icons.tsx.
