Fixes #1076 (all five items).

What changes

1. Quoted braces in at-rule headers (item 3, both engines). enclosed_only_by_at_rules (crates/foundation/src/css/scan.rs) now records where each block's header starts during the quote-aware scan it already runs (a newline ends an unterminated string, as in last_unquoted_delimiter). Before, it searched back with a quote-unaware rfind, so @supports (content: "a;b") { .b { … } } lost .b's selector. New cases are in enclosing_selector_matches_node.

2. Inactive at-rule candidates in the pattern walk (item 2, URL engine). The stripe-only repeating_gradient_applies becomes computed_paint_applies. A glow needs the shadow property its snippet names to be something other than none, a halo needs a radial-gradient background image, and a grid needs a gradient background image. A value the capture did not record still answers yes. So does a ::before/::after part for the three new rules, because a content: '' box is never recorded. codex-grid-background used to offer only the first grid block, so the walk never got a second candidate. It now offers every grid block lazily through grid_background_hits. The frozen scanCssTextForGridBackground export still returns the first.

3. Code in a scrolling page shell (item 4, URL engine). If a scroll-region ancestor is the page shell (clipping_container_is_page_shell), it no longer exempts code inside it. The existing code tests then decide, so a line that runs past the screen edge is reported.

4. Wordmark name match (item 5, URL engine). If og:site_name or application-name is present, that is the site name and the title is not read. Otherwise a title with one part still counts whole. In a title with several parts, a part counts only if the host name contains it. A faint 100px "Pricing" on "Pricing | Northwind" now reports as a warning instead of an advisory.

5. Scaled 1px text (item 1, URL engine). I checked this against main after Fix small measurement defects from craft run 1009 (round 13, branch D) #1151 landed. Fix small measurement defects from craft run 1009 (round 13, branch D) #1151 fixed the cramped-padding flush form: it now keeps sub-1px text that has a measured rect of 1px or more, text_descendants_flush_sides in quality.rs. The rest was still open: the sub-1px descendant test in no_font_size and text-occlusion's top_own_text both read the raw computed size. A new helper, painted::drawn_at_most_1px, now serves those readers and the occlusion victim test, so text a transform enlarges counts as text. The new fixture is text-occlusion-scaled-1px.html, with unit cases in painted.rs and page_checks.rs. The browser test fails with the source change stashed. This part touches only browser code, so the hook cost is unchanged.

Tests

• Fixtures: text-occlusion-scaled-1px.html, pattern-walk-inactive-at-rules.html, text-overflow-code-page-shell.html, low-contrast-title-wordmark.html. crates/browser/tests/round11_edge_cases.rs drives them in a real browser. All three tests fail with the source changes stashed and pass with them.
• New unit tests in driver.rs, decorative_text.rs and css_scan.rs.
• Oracle: eight new fixture goldens were recorded from a release build and reviewed by hand (see DELTAS.md). No existing golden moved, and the frozen vectors replay unchanged. The directory sweeps are accepted deltas that were already behind main, so I did not re-record them.
• docs/CLI-CONTRACT.md: new "Round 11 deferred edge cases" bullet. The wordmark site-name parenthetical is updated.

Hook cost

Item 3 reaches the text and static-HTML engines. Below are rule_cost --runs 9 tests/fixtures/antipatterns numbers (261 inputs) for main and this branch, run on the same machine and the same fixture set. The differences are within noise.

engine / unit	main mean / p50 / p95 ms	branch mean / p50 / p95 ms

Note

Medium Risk
Touches core detection heuristics (pattern gating, wordmark classification, text occlusion/overflow, and CSS selector recovery) with broad fixture coverage but subtle behavior changes on real pages.

Overview
Addresses corpus round 11 deferred edge cases (#1076) across CSS parsing, HTML pattern detection, and several browser checks.

Pattern walk: Inactive @media/@supports rules no longer suppress visible candidates. Stripe-only repeating_gradient_applies is generalized to computed_paint_applies, which also requires computed glow shadows, radial halos, and grid gradients to match what the rule declares. Grid backgrounds are offered lazily via grid_background_hits so the walk can skip dead candidates and still find the next match.

CSS structure: enclosed_only_by_at_rules tracks header start positions with quote-aware scanning so selectors inside at-rules with quoted ; or } in the header (e.g. @supports (content: "a;b")) are not lost.

Text checks: drawn_at_most_1px centralizes “1px unless transform scales it up” logic for unpainted text, occlusion victims, and overlay text—so font-size: 1px with scale: 16 is treated as readable. Code inside a full-page overflow: auto shell is no longer skipped as if it lived in a normal scroll region; overflow on code can still flag.

Wordmarks / low contrast: Site naming prefers non-empty og:site_name / application-name and ignores title parsing when set. Multi-part titles contribute site names only for segments corroborated by the hostname; faint page titles like “Pricing” on Pricing | Acme are not advisory wordmarks.

Tests: New antipattern fixtures plus round11_edge_cases.rs browser integration tests and targeted unit tests in driver, decorative_text, css_scan, painted, and page_checks.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; no new actionable issue was found.

Summary

Addresses five detector edge cases, with regression fixtures, browser tests, and updated behavior notes.

• CSS rules inside at-rules keep their selectors when headers contain quoted punctuation.
• Pattern checks pass over inactive glow, halo, and grid candidates to find what paints.
• Code that runs offscreen is checked even inside a scrolling page shell.
• Faint title text counts as a wordmark only when it names the site.
• Text enlarged from 1px is counted at the size it is drawn.
