+## WezTerm Profile Theme
+
+Sets the WezTerm terminal theme when a Claude session starts or resumes, by emitting an OSC 1337 `SetUserVar` escape sequence. WezTerm fires its `user-var-changed` Lua event and applies the matching color scheme and background image from `wezterm.lua`.
+
+**Derives profile name** from `CLAUDE_CONFIG_DIR` (e.g. `~/.claude-octopus` → `octopus`). No-ops for the default profile.
+
+**Writes to `/dev/tty`** to reach WezTerm directly, bypassing Claude Code's stdout capture. Safe in non-WezTerm terminals — the sequence is silently ignored.
+
+**Configure per profile** in `~/.claude-<name>/settings.json`:
+```json
+"SessionStart": [
+  { "hooks": [{ "type": "command", "command": "~/.claude/hooks/set-wezterm-profile.sh" }] }
