+
+## Summary
+- Updated Text to Speech V2 CSS so `#text2speech-V2StatusLog` fills the available height of `#text2speech-V2StatusLogContent`.
+- Kept status log overflow internal to the textarea and prevented the status content container from leaving unused vertical space.
+- Preserved existing Status accordion controls and did not change schema, payload, or Workspace Manager contracts.
+- Added Playwright coverage for status log fill height, internal scrolling under many entries, and no page-level overflow regression.
+
+## Scope Notes
+- Text to Speech V2 runtime change is CSS-only.
+- No JavaScript runtime files changed.
+- No schemas, payload defaults, samples, or workspace contracts changed.
+- No `start_of_day` files changed.
+
+## Playwright Impacted
+Yes.
+
+Validated behavior:
+- `#text2speech-V2StatusLog` fills `#text2speech-V2StatusLogContent`.
+- Many status entries scroll inside the status log textarea.
+- Adding many status entries does not create page-level overflow when the page otherwise fits.
+
+Expected pass behavior:
+- Text to Speech V2 keeps the Status accordion controls working.
+- The status log uses the available panel height and scrolls internally.
+- `npm run test:workspace-v2` passes.
+
+Expected fail behavior:
+- Leaving unused vertical space below the status log fails layout assertions.
+- Regressing internal status log scrolling fails the scroll assertions.
+- Letting status log content grow the page fails the page overflow assertion.
+
+## Validation
+- PASS: `npx playwright test tests/playwright/tools/WorkspaceManagerV2.spec.mjs --project=playwright --workers=1 --reporter=list -g "shows safe empty Text to Speech V2 state"` -> 1 passed.
+- PASS: `npm run test:workspace-v2` -> 37 passed.
+- PASS: `git diff --check` -> no whitespace errors; CRLF conversion warnings only.
+
+## Full Samples Smoke Test
+Skipped. This PR is limited to Text to Speech V2 status log CSS/layout and targeted Workspace V2 Playwright coverage is the required validation gate.
+
+## Manual Validation
+1. Open Text to Speech V2.
+2. Confirm the Status log fills its accordion content area.
+3. Trigger enough status messages to exceed the visible log area and confirm only the log scrolls internally.
+4. Confirm the page itself does not gain a scrollbar solely because the Status log has many entries.
