[patcapulong]

Hide ::after pseudo-elements that Mintlify may have added to accordion and expandable summaries, which were causing duplicate chevrons alongside our custom ::before chevrons.

• Added ::after hiding rules for accordion-group summaries
• Added ::after hiding rules for standalone accordion summaries
• Added ::after hiding rules for API reference expandable sections
• Added additional icon element selectors (span[data-icon], [data-slot="icon"])

Greptile Summary

This PR patches mintlify/style.css to suppress duplicate chevrons introduced by a Mintlify update, which began emitting ::after pseudo-elements alongside the existing ::before custom chevrons. All changes are purely defensive CSS — hiding ::after on accordion-group, standalone accordion, and API-playground summary elements, plus covering new icon-slot selectors (span[data-icon], [data-slot="icon"]). The sidebar selector block was also updated from targeting > svg directly to covering the new div:has(> svg) wrapper Mintlify introduced.

Confidence Score: 5/5

Safe to merge — pure CSS defensive fixes with no logic changes or functional risk.

All changes are additive CSS display: none / content: none rules targeting Mintlify-generated pseudo-elements and icon slots. No application logic, no OpenAPI spec, and no MDX content is touched. The selectors are appropriately scoped and the fix directly addresses the stated double-chevron symptom.

No files require special attention.

Vulnerabilities

No security concerns identified.
