# Task 02: Freeze disabled native transcript

## Acceptance

- Disabling auto-scroll from the bottom prevents native browser anchoring from
  advancing the transcript after a live message arrives.
- Enabled auto-scroll remains bottom-pinned.
- Desktop and Pixel-5 mobile tests cover the bottom-anchor case.

## Verification

```bash
cd apps
pnpm install --frozen-lockfile
cd web
pnpm e2e:run tests/chat/auto-scroll-toggle.spec.ts -- --grep 'disabling while genuinely at the bottom'
pnpm e2e:run tests/chat/mobile-auto-scroll-toggle.spec.ts
```
