"""Static-text acceptance: chat.js contains per-turn bubble markers.

These checks do not require a browser or network. They verify the generated
JavaScript source ships the expected per-turn semantics introduced in Phase 3:
- The bubble tooltip uses 'Turn — input:' (per-turn label, not session total).
- The bubble chip argument is 'u.input_tokens | 0' (per-turn source, not the
  session accumulator).
