feat(viewer): host-overridable ss:aside-head slot atop the sidebar#172
Merged
Conversation
Mirrors ss:aside-foot at the top of the sidebar, above the session list, so an embedder can project a header (e.g. a workspace picker + Home link). The slot is bare with no fallback children, so with no projection it has zero height and self-hosted rendering is byte-identical to before. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Adds a new host-overridable named slot
ss:aside-headat the top of the sidebar, above the session list — mirroring the existingss:aside-foot. Registered in bothviewer/src/host.ts(SLOTS) and the hand-writtenviewer/embed.d.tsso the publishedSlotNameunion includes it.Self-hosted parity is preserved: the insertion is a bare
<slot name={SLOTS.asideHead} />with no fallback children and no wrapper element/CSS, so with no projection it has zero height and rendering is byte-identical to before. An embedder can project a sidebar header here — e.g. a workspace picker and a pinned Home link.Includes an e2e spec (
e2e/embed-aside-head-slot.spec.ts) covering the no-projection (empty) and projection (above the session list) cases, and a changeset (minor).🤖 Generated with Claude Code
