[maria-rcks]

Summary

• Match the thread tooltip folder icon stroke color to the other metadata icons.

Why

The project favicon fallback used a dimmer inherited color than the server, branch, and provider icons.

Verification

• vp fmt apps/web/src/components/SidebarV2.tsx --check
• vp lint apps/web/src/components/SidebarV2.tsx --report-unused-disable-directives
• vp run --filter @t3tools/web typecheck

Browser testing was skipped at the requester’s direction.

Note

Fix folder icon stroke color in thread tooltip sidebar

Adds stroke-muted-foreground to the ProjectFavicon element in SidebarV2ThreadTooltip so the folder icon renders with the correct muted color instead of the default stroke.

Note

Low Risk
Single Tailwind class on a sidebar tooltip icon; no logic, data, or API changes.

Overview
In Sidebar V2 thread hover tooltips, the project row’s ProjectFavicon now includes stroke-muted-foreground so the folder fallback stroke matches the server, branch, and other metadata icons instead of looking dimmer from inherited stroke color.

Approvability

Verdict: Approved

Single-line CSS class addition to fix icon color styling. This is a trivial UI adjustment with no runtime behavior impact.
