 All tasks in this phase are parallelizable [P] since they are independent E2E spec files.
 
 - [x] T054 Create Page Object Model in `frontend/e2e/pages/analyzer-page.ts` — encapsulates all page interactions: `pasteHeaders(text)`, `dropFile(path)`, `clickAnalyse()`, `pressCtrlEnter()`, `selectTests(ids)`, `deselectAll()`, `selectAll()`, `toggleDns()`, `toggleDecodeAll()`, `waitForResults()`, `getResultCards()`, `expandCard(index)`, `collapseCard(index)`, `searchReport(query)`, `exportJson()`, `exportHtml()`, `clearCache()`, `getCaptchaModal()`. Copy test fixture files to `frontend/e2e/fixtures/sample-headers.txt` and `frontend/e2e/fixtures/sample.eml`
-- [ ] T055 [P] Create `frontend/e2e/paste-and-analyse.spec.ts` — test US1+US3+US4 primary flow: paste sample headers → click Analyse → verify progress indicator appears with test names → verify report renders with severity-coloured cards → expand/collapse a card → verify hop chain visualisation rendered. Also test Ctrl+Enter keyboard shortcut triggers analysis. Assert on UI effects of SSE progress (progress bar increments, test name updates)

 - [ ] T056 [P] Create `frontend/e2e/file-drop.spec.ts` — test US1 file drop flow: dispatch synthetic DataTransfer+drop events on drop zone with `.eml` fixture → verify textarea auto-populates with header content → click Analyse → verify report renders. Test rejection of unsupported file types (e.g., `.pdf`)
 - [ ] T057 [P] Create `frontend/e2e/test-selection.spec.ts` — test US2: open test selector → verify 106+ tests listed → click Deselect All → select 3 specific tests → analyse → verify only 3 results in report. Test search/filter narrows visible tests. Test DNS and decode-all toggle states persist through analysis
 - [ ] T058 [P] Create `frontend/e2e/report-interaction.spec.ts` — test US4 report features: expand all cards → collapse all → search for a term → verify filtered results → clear search → export JSON → verify downloaded file is valid JSON. Export HTML → verify downloaded file contains styled content
