* Fix: detect placeholder contrast (#790) `detect` never read `::placeholder` color, so pale placeholders passed. Score them with the same WCAG math as body text, without host class/clip heuristics. Prepared with AI assistance. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix: match descendant ::placeholder hosts (#790) `.form ::placeholder` kept the ancestor as the host. Reuse the hover combinator star-fill so the color lands on the inputs inside. Prepared with AI assistance. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix: placeholder-shown and gradient alpha (#790) Browser scans skip when :placeholder-shown is false, so a live filled field does not keep the HTML value attribute's empty state. Translucent placeholders flatten over each gradient stop before scoring. Prepared with AI assistance. Co-authored-by: Cursor <cursoragent@cursor.com> * Fix: trailing combinator only for ::placeholder hosts (#790) `star_empty_compounds` turned `.label + ::placeholder` into `.label *+*`. Fill only a trailing empty compound so adjacent-sibling hosts still match. Prepared with AI assistance.

browser-bundle: the page-side JavaScript of the detector
Plain JavaScript that runs inside a page or the extension: the DOM probe the
wasm rule core calls back into, the page snapshot producer, the
visual-contrast sampling IO, the overlay UI, the scan API and the extension's
offscreen document. Measurement and presentation only; every rule decision
is a call into the wasm rule core built from crates/core (docs/ENGINE.md).
Two consumers:
crates/browserembeds15-snapshot.js(the snapshot producer the URL engine injects; no WebAssembly runs in the page).crates/bundle(theimpeccable-bundlelibrary) embeds every file here withinclude_str!and concatenates them, in filename order, with the wasm core into the in-page bundle plus the extension'sextension/detector/pieces.cargo xtask bundleis its caller inside this workspace: it writesdist/detect-antipatterns-browser.js, copies that bundle to the trackedcrates/live/assets/detect-antipatterns-browser.jsthe engine embeds, and writes the extension pieces. A downstream crate with its own rule pack calls the library directly (docs/ENGINE.md).
Because the files are embedded, a new one here has to be added to
PAGE_JS in crates/bundle/src/lib.rs (and to the order it is concatenated
in); a test fails when the two lists disagree.
15-snapshot.js lists the computed-style properties the rules read; the
bundle build checks that list against the core's and fails when they drift.
