Greptile Summary

This PR adds a sidebar icon for the Discoveries API reference group by introducing a new SVG file (IconSquareChecklistMagnifyingGlass.svg) and a single CSS rule in style.css that mirrors the established pattern for all other sidebar group icons. No logic, content, or schema changes are included.

Confidence Score: 5/5

Safe to merge — purely additive documentation styling change with no logic or content impact.

Two-file change: a new SVG and a single CSS rule, both following the exact established pattern used by every other sidebar group icon. No P0 or P1 findings.

No files require special attention.

Important Files Changed

Filename	Overview
mintlify/images/icons/IconSquareChecklistMagnifyingGlass.svg	New 20×20 SVG icon for the Discoveries sidebar group; matches existing icon dimensions and will render correctly under the global CSS filter.
mintlify/style.css	Adds CSS rule wiring the new SVG as background-image for the Discoveries sidebar group button::before pseudo-element, consistent with all other group icon rules.
