Reusable widget for panes that need N runtime tab instances of the same kind. First consumer is the Claude pane (primary + 0..N secondaries per D-41); the generic shape lets other panes adopt it later without reinventing tab strips. Includes: - Design doc with API sketch, rendering, interaction, persistence boundary, integration sketch for the Claude pane, and three open questions (keyboard scoping for nested cases, overflow, density). - Wireframe of the Claude pane with primary (pinned) + 2 secondaries + add button, accent border on the active tab. - Architecture diagram (sketch mode) showing the host / widget / controller / IPC boundary that keeps the widget domain-free.
