# Phase 6 CSS Namespace Audit

**File audited:** `template/app.css` (399 lines, 60 top-level rule blocks, 68 effective rules counting nested `@media`).

**Audit method:** Python brace-scanner that walks every top-level rule and every rule nested inside `@media`/`@supports`. Each selector is split on commas; every comma-part must either contain `#polisci-root` or be in the allowed bare set (`html`, `body`, `*`, `:root`). At-rules (`@media`, `@keyframes`, `@font-face`, `@supports`, `@import`, `@charset`, `@page`) are allowed at the top level.

## Result

| Metric | Count |
|---|---|
| Top-level rule blocks | 60 |
| Scoped under `#polisci-root` | 68 |
| Allowed at-rules (`@media`) | 1 |
| **Violations (unscoped)** | **0** |

No fixes required. The stylesheet is fully namespaced under `#polisci-root`, including the comparison styles appended by Phase 5 and the responsive `@media (max-width: 768px)` block whose inner rules are all prefixed.

## Embed contract status

- `template/app.css` — passes (0 unscoped rules)
- `template/app.js` line 37 — `state.BASE = root.dataset.base || './data/'` honors host-provided base path
- `template/compare.js` line 30 — same pattern honored
- `results/119/_embed_test.html` — smoke-test host page written for manual visual inspection
