phase: 149_sync_progress_box

All verification complete. The `ink-soft`/`--surface` pair the box uses is already pinned AA by the existing theme E2E suites (8.2:1 dark, ~6.9:1 light). Everything is green — no fixes were needed.

**Phase 149 final verification report**

- Verified (no re-work needed): `#sync-progress` box wiring (single `setSyncLabel` writer with `running` flag; `is-running` class travels with the spin; aria-label owned by the writer), the panel/icon-only-button CSS, and the 5-test dedicated E2E; all 6 pre-existing sync E2Es' running pins migrated to the box, settled pins untouched.
- Dedicated E2E: `uv run pytest tests/e2e/test_sync_progress_box.py -v --no-cov` → **5 passed in 198.6 s** (isolation, slow-proxy mock; under the 600 s budget).
- Full suite: `uv run pytest --cov=app --cov-report=term-missing` → **3463 passed, app/ coverage 99%** (>90% gate).
- Migrated sync E2Es, each in isolation: `test_sync_button` 3 passed, `test_sync_cancel` 3, `test_sync_chunk_progress` 2, `test_sync_label_mobile` 4, `test_sync_summary_visibility` 3, `test_sync_upload_progress` 4 — all green.
- Lint/types: `uv run ruff check .` → All checks passed; `uv run pyright` → 0 errors.
- Criteria: in-flight spinner-only button + full untruncated wrapped box (desktop & mobile 390×844, `scrollWidth ≤ clientWidth`) ✓; settle byte-identical ("Synced HH:MM" + `3 added`, box hidden, aria restored) ✓; `#sync-result` sole live region (box `aria-hidden`), mid-run reload re-attaches ✓; WCAG (AA contrast both themes via the pinned ink-soft/surface pair, focus-visible, reduced-motion kill intact at styles.css L2201) ✓; cancel/409/error/upload/status API unchanged (green suites above) ✓.
- Documentation: README.md reviewed in full (sync-states paragraph now matches the shipped UI; env-var table matches `app/config.py` and covers all `.env.example` vars; pages/commands verified) and AGENTS.md reviewed in full — **verified consistent, no changes needed**.
- Notable: no defects found in this or prior work; no live infrastructure touched.
- Next pending phase: none — `todo/` will be empty once the harness moves 149 (only 149 was pending).
