+# Self-Service Profile Page — Implementation Plan
+
+## Tasks
+
+### Task 1: Create `manage/base.html` template with navigation
+- Create `src/porchlight/templates/manage/base.html`
+- Extends `base.html`
+- Adds `<nav>` block with Profile and Credentials links
+- Style nav links in `style.css` (minimal, consistent with existing design)
+
+### Task 2: Update `credentials.html` to extend `manage/base.html`
+- Change `{% extends "base.html" %}` to `{% extends "manage/base.html" %}`
+- Verify credentials page still renders correctly
+
+### Task 3: Create `profile.html` template
+- Extends `manage/base.html`
+- Form with fields: given_name, family_name, preferred_username, email, phone_number, picture, locale
+- Read-only username display
+- HTMX form submission with status target
+- HTML5 input types and validation attributes
+
+### Task 4: Add GET and POST routes for `/manage/profile`
+- `GET /manage/profile` — fetch user, render profile.html with pre-filled fields
+- `POST /manage/profile` — validate form data, update user via repo, return HTMX partial
+- Auth guard via `get_session_user()` on both routes
+- Server-side validation for email format, URL format, string lengths
+
+### Task 5: Add nav CSS styles
+- Style the manage nav bar (links, active state, spacing)
+- Keep consistent with existing design system
+
+### Task 6: Add E2E tests (`profile.spec.js`)
+- Page structure and form fields
+- Auth guard redirect
+- Successful profile update and persistence
+- Validation error handling
+- Navigation between profile and credentials
+
+### Task 7: Seed test user profile data in `setup_db.py`
+- Add profile fields to an existing test user so tests can verify pre-filled data
+
+### Task 8: Run full test suite and verify
+- `uv run pytest` (Python tests)
+- `npx playwright test` (E2E tests)
+- Fix any failures
+
+## Verification
+- All existing tests continue to pass
+- New E2E tests pass
+- Profile page renders, submits, and updates correctly
