# Quick 261006-s0v: Remove ML copy-from locale UI

`mltext` and `mlmarkdown` now show one locale picker. The second unlabeled dropdown and Copy button are gone, so switching language cannot blank the field you are editing.

## What was built

**Task 1 (commit 2f03128)**
- `MLTextField.vue` and `MLMarkdownField.vue`: dropped `copyFrom`, `otherLocales`, `copyLocale`, the copy-from select, and the Copy button. Locale broadcast and nested `Record<string,string>` values are unchanged.
- `MLFields.test.ts`: asserts copy selectors/buttons are absent; editing Polish keeps English.
- `docs/backend/forms.md`: removed the Copy-from-locale sentence.
- `modules/boardwalk/dist` rebuilt (`index-CRrQr2H1.js`).

## Verification

| Command | Result |
|---|---|
| `npm --prefix admin test -- tests/form/MLFields.test.ts` | 11 passed |
| `npm --prefix admin run typecheck` | pass |
| `scripts/check-admin-dist.sh` | matches a fresh build |
| `go test ./cmd/summer -run TestDocsTree` | pass |

## Deviations from Plan

None. Typed `gsd-planner`/`gsd-executor` are not available in this Cursor session; the orchestrator wrote the plan and executed it inline with `workflow.use_worktrees=false`.

## Known Stubs

None.
