// Action chips: the Claude tools a helper may call, and the mapping from the
// model's tool_use blocks to the `actions` array shipped inside the encrypted
// message payload. The CLIENT is the whitelist that matters (ui.js
// sanitizeActions) — this file only decides what the model can *propose*.
// Chips never auto-run: the member taps to apply, which is why the set is
// small, harmless, and reversible. Dependency-free so tests can import it.

// Keep the theme list + descriptions in step with web/static/ui.js THEMES.
// Exported so the deterministic command floor (commands.mjs) validates against
// the same lists the model tools do.
