No-AI skill tracer: SKILL.md, theme presets, sample data, Seam 1 page check

- rpa-dashboard-no-ai/SKILL.md: trigger description and the workflow in spec
  order (scan, report/keep-or-restyle, colours, stack, sections, build, wire,
  verify).
- templates/themes.md: Tebra Sky and Superbill Ember, light and dark blocks.
- templates/palette.py: derives a custom palette from one brand hex and
  checks text contrast in light and dark.
- dashboard.html: built-in sample data so a page with no bot works on first
  open; cleared batches in the donut; component tokens so Ember is a
  token-only swap; accessible names for KPI cards, nav, steps, log, search
  and the dark toggle.
- bridge.py: placeholders inside string literals, so it passes the lint hook
  unfilled.
- tests/page_check: Seam 1 harness (fake Qt bridge, light/dark/narrow).
- tests/evals: Seam 2 runner and fixture a-empty.

+# Tests
+
+Run everything from the repo root:
+
+```
+uv run --with pytest --with playwright pytest tests
+```
+
+- `test_*.py`: assert-based self-checks for template logic (lint of unfilled Python
+  templates, the custom palette, presets in step with the template).
+- `page_check/`: **Seam 1.** Loads a dashboard page in headless Chromium with no
+  backend, pushes contract envelopes through `window.__pyMsg`, and asserts on what
+  is visible. Every case runs in light, dark and narrow (800px) mode.
+  - By default it checks the no-AI template, filled with test values. To check a
+    generated page instead, set `PAGE_CHECK_HTML=path/to/dashboard.html`.
+  - The page sees a fake Qt bridge. Every action the page sends is recorded in
+    `window.__calls` as `[slot, ...args]`.
+  - To add a case, write a `test_*.py` file in `page_check/` that uses the `page`
+    and `push(event, data)` fixtures from `conftest.py`.
+- `evals/`: **Seam 2.** Runs the skills on a fixture project with `claude -p`,
+  then grades the reply and runs the page check on the page it built:
+
+  ```
+  uv run --with pytest --with playwright python tests/evals/run_eval.py a-empty
+  ```
+
+  Results go to `evals/results/<fixture>.json`. To add a fixture, add an entry to
+  `FIXTURES` in `run_eval.py`.
+- `fixtures/<letter>-<name>/`: small test projects for the evals.
