Bulk-instruments the remaining 49 demo pages with `<meta name="perm-axes"
content="dir" />`, bringing total coverage from 15/66 demos to 63/66.
Only checkbox, radio-group, and switch remain skipped — they have no
demo directory at `/test/soma/` (pre-existing gap, unrelated).
## Runner change
`scripts/permutation-check.ts` now allows meta-only demos (no
`data-perm-step` annotations) to participate: if a demo declares any
axis via the meta tag, the runner still visits its baseline + RTL
variants and runs the `[initial seed]` morfo validation at each, even
without a click cycle. This gives passive LTR/RTL coverage to demos
where a click-driven perm sequence doesn't apply naturally (leaf
components like Avatar, Progress, Meter; grid/list components; pickers
with inline controls).
Key change in `probeDemo()`: a demo is "instrumented" if EITHER the meta
tag OR at least one `data-perm-step` is present. Step-only demos get
the v1 click cycle at baseline; meta-only demos get the v3 axis matrix
with passive `[initial seed]` validation at each variant; declaring
both is the full treatment.
## Bulk instrumentation
For each of the 49 remaining demos, added:
```svelte
<svelte:head>
<title>… · Soma</title>
<meta name="perm-axes" content="dir" />
</svelte:head>
```
Baseline axis (`dir`) only. Demos that benefit from additional axes
(`orientation`, `disabled`, etc.) opt in incrementally — the bulk edit
doesn't touch their `$state` seeds, only adds the meta tag.
## Coverage delta
| Metric | Before | After |
|--------|-------:|------:|
| Instrumented demos | 15/66 | **63/66** |
| URL variants | 35 | **131** |
| Step validations | 106 | **202** |
~4× increase in URL variants visited per CI run. Most new demos
contribute 2 variants each (ltr + rtl), validating morfo under direction
flip. Fully-instrumented demos (tabs, toolbar, toggle-group, listbox)
still contribute 3-4 variants with click cycles.
## Deferred
- `context-menu` — right-click activation needs a `data-perm-mode='contextmenu'`
runner extension.
- `navigation-menu` — hover-driven, same as Tooltip. Tooltip was
instrumented via `data-perm-mode="focus"` + long settle; NavigationMenu
could follow the same pattern in a targeted batch.
- `color-picker` — complex pointer state machine on Area / ChannelSlider.
Meta-only covers the baseline structure.
## Verification
- `npm run check`: 0 errors in soma/morfo/test-route scope.
- `npm run smoke`: 65/65 routes.
- `npm run morfo:check`: 66/66 morfos.
- `npm run perm:check`: 63/63 instrumented demos · 202 steps · 131 variants.
