PR Summary

Low Risk
Presentation-only changes to Signature/FunctionSignature with no auth, data, or API impact; main risk is minor doc UI regressions if container detection (!name && !type) misclassifies edge cases.

Overview
Returns rows in function signatures now render in the same grouped Signature container as parameters instead of being split into a separate block, so CSS can treat them as a footer attached to the items above.

New SignatureItem styles apply to top-level kind="return" items (not nested under .children): full-bleed negative horizontal/bottom margins, flat top corners, and a top divider. FunctionSignature drops the loop that partitioned items into attributes vs returns and always maps all items under one titled Signature.

Signature now treats missing name and type as the grouping root (optional title), replacing the previous title-only branch. SignatureRoot only renders the title heading and wires aria-labelledby when a title is present.

Pull request overview

This PR refactors the signature rendering components so that “Returns” entries can be rendered inline with other signature items (enabling the new “full-bleed footer” styling), and improves the SignatureRoot markup so it only wires up aria-labelledby (and renders a title element) when a title is actually present.

Changes:

• Simplify FunctionSignature to always render a single Signature group containing all items (including returns).
• Update SignatureRoot to conditionally render the title element and only set aria-labelledby when title exists.
• Add CSS to style a top-level return item as a full-bleed footer attached to preceding items, and adjust Signature to treat “root vs item” based on name/type rather than title.
