// Tier 2 of the subconscious three-tier visibility design (see
// docs/tasks/subconscious-surfacing-threshold.md): a persistent, interactive
// event log — the shell's equivalent of the TUI "cockpit". Shows surfaced
// subconscious events (pass snapshots, reflections, archivist syntheses,
// surfacings) from past turns. Each entry click-expands to its full text,
// closing docs/bugs.md B-005 ("subconscious messages not expandable").
// Fed by Ai.subconsciousEvents; the live Tier-1 ticker is snapshotted into
// it on pass end.
