[verified] Security hardening + UX/UI polish

Security (requesting-code-review pipeline + independent reviewer):
- Fix path traversal on file upload (basename sanitize + resolve-containment)
- Fix IDOR: org + owner scoping on all group/chat routes (_authorize_group/_get_owned_group),
  hide other users' personal groups in listings
- Remove XSS via v-html in Chat task (text interpolation)
- Add test_security.py (traversal + cross-user denial) — all pass

UX/UI (ui-ux-pro-max + frontend-dev-verification):
- Global: focus rings, 44px touch targets, hover/press transitions, input focus glow,
  prefers-reduced-motion, skeleton loaders, empty states, back links, spinner
- Login: password toggle, autocomplete, spinner, disabled-when-empty
- Cards lift on hover; dashboard skeleton + empty state; analyze button spinner

All backend tests pass (m0/m1/routes/security/e2e); frontend builds; served SPA verified via curl.

+# 2026-08-07 — Security hardening + UX/UI polish
+
+## Summary
+Ran the `requesting-code-review` (security) + `ui-ux-pro-max` (design) + `frontend-dev-verification`
+pipelines against the built Sales Trainer app. Fixed real security vulnerabilities and applied
+accessibility/touch/visual polish. Committed as `[verified]`.
+
+## Security audit — found & fixed
+1. **Path traversal on file upload** (HIGH): `create_group` used the raw client `file.filename` in
+   `dest = upload_dir / f"{user}__{file.filename}"` → an attacker-provided name like `../../evil.txt`
+   could escape the upload directory. FIXED: strip to basename (`Path(name).name`), reject names
+   containing `/` or `\`, and add a `resolve().relative_to(upload_dir)` containment check.
+2. **IDOR — org/owner scoping missing** (HIGH): `list_personas`, `get_persona`, `update_persona`,
+   and the chat routes did not verify a group belonged to the caller's org; personal groups
+   (`owner_user_id`) were readable by any same-org user. FIXED: centralized `_authorize_group` /
+   `_get_owned_group` (org scope, super_admin bypass, owner-only for personal groups) applied to all
+   group + chat routes; `list_groups` and `win_lose_board` now hide other users' personal groups.
+3. **XSS hygiene** (MEDIUM): `Chat.vue` used `v-html="taskText"`. FIXED: switched to text
+   interpolation; removed server HTML in the opener-task string.
+4. Confirmed no hardcoded secrets, no eval/exec, no shell injection, no self-registration (register→404).
+
+## UX/UI (ui-ux-pro-max applied)
+- Global `style.css`: visible focus rings (a11y), 44px min touch targets, button/card hover +
+  active-press transitions (150–300ms), input focus glow, `prefers-reduced-motion` support,
+  skeleton loaders, empty-state block, back-link button, spinner, responsive mobile margins.
+- Login: password show/hide toggle, autocomplete attrs, spinner, disabled-when-empty.
+- Personas/GroupEdit/Dashboard: `.lift` card hover, back-navigation links, proper empty states
+  (skeleton loaders on dashboard), spinner on analyze button.
+- Chat: back link, spinner on finish button, disabled-after-debrief.
+
+## Verification
+- `test_security.py` ADDED: traversal filename rejected (no file escapes), cross-user personal-group
+  access → 403, personal group hidden from other users' listing. ALL PASS.
+- Full suite re-run: test_m0 / test_m1 / test_routes / test_security / test_e2e ALL PASS.
+- Frontend `npm run build` ok (11 chunks). Served-page verification via curl: `GET /` 200,
+  register 404, login 200; new CSS classes (`btn-back`, `card.lift`, `empty-state`,
+  `focus-visible`, `prefers-reduced-motion`, `skeleton`) present in served bundle; no `v-html` in
+  any built JS chunk.
+- Browser visual check was BLOCKED by an environment issue: Hermes browser proxy resolves to
+  `camo.moreminimore.com/tabs` (HTTP 500) and cannot reach localhost. Rendered verification done
+  via served-HTML/DIST inspection instead.
+
