* 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.

* 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.

* 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.

* 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.
