## Summary
- add adaptive baseline compare presentation modes with `auto`, `dense`, and `compact` route handling on the existing matrix page
- compress support surfaces with staged filters, grouped legends, last-updated and passive refresh cues, compact single-tenant results, and dense multi-tenant scan rendering
- extend the matrix builder plus Pest and browser smoke coverage for visible-set-only compact and dense workflows
## Filament / Laravel notes
- Livewire v4 compliance preserved; no legacy Livewire v3 patterns introduced
- provider registration is unchanged; no `bootstrap/providers.php` changes were needed for this feature
- no globally searchable resources were changed by this branch
- no destructive actions were added; the existing compare action remains simulation-only and non-destructive
- asset strategy is unchanged; no new Filament assets were introduced
## Validation
- `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Filament/BaselineCompareMatrixPageTest.php tests/Feature/Baselines/BaselineCompareMatrixBuilderTest.php tests/Feature/Guards/ActionSurfaceContractTest.php tests/Browser/Spec190BaselineCompareMatrixSmokeTest.php`
- `80` tests passed with `673` assertions
- integrated browser smoke run on `http://localhost/admin/baseline-profiles/20/compare-matrix`
## Scope
- Spec 191 implementation
- spec contract updates in `spec.md`, `tasks.md`, and the logical OpenAPI contract
