The HELLO_LEADING phrase was the showcase-assistant catch-all
boilerplate ('I can help you with weather lookups...') that other
tests in this PR explicitly guard AGAINST. The dedicated d5-all.json
fixture for 'Say hello in one short sentence' now returns a distinct
non-boilerplate greeting; the spec asserts that distinct phrase, so a
fixture-priority misroute fails loudly instead of passing by accident.
Rewrites both headless specs to the pill-driven plan from
.claude/specs/lgp-test-genuine-pass.md (Family-1F).
headless-simple (4 tests):
1. page loads with custom composer + 3 pills visible
2. hello pill -> assistant bubble starts with the greeting leading phrase
3. joke pill -> assistant bubble contains the deterministic joke
4. fun fact pill -> assistant bubble contains 'Honey never spoils!'
headless-complete (5 tests):
1. page loads with custom composer + 4 pills visible
2. weather pill -> WeatherCard with Tokyo / Sunny / 68F + narration
3. AAPL pill -> StockCard with AAPL / $189.42 / +1.27% + narration
4. highlight pill -> HighlightNote with 'ship the demo on Friday' + narration
5. revenue chart pill -> ChartCard with 'Quarterly revenue', subtitle,
month labels Jan-Jun + narration
Each test asserts on the headless-specific testids introduced in the
preceding commit, so a regression that demotes the headless surface
back to the default CopilotChat surface fails every tool test. Each
pill exercises a different render-hook path so regressions surface
test-by-test.
No .skip() — all 9 tests are live.
The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
