Best possible solution:

Retain the CSS-only implementation if a maintainer’s final visual check confirms it matches the intended sidebar-menu language at supported viewport sizes and themes.

Do we have a high-confidence way to reproduce the issue?

Not applicable: the PR changes presentational styling, and its supplied captures directly show the intended before/after UI state.

Is this the best way to solve the issue?

Yes: keeping the change CSS-only is the narrowest maintainable way to align this existing roster popover with adjacent Control UI menus without changing presence behavior.

What I checked:

• Focused UI surface: The proposed branch changes only the presence-roster CSS rules, keeping roster behavior and data flow outside the patch boundary. (ui/src/styles/layout.css:1982, f7a450a675a5)
• After-fix behavior proof: The PR body supplies before/after captures for a three-user injected presence payload in dark and light themes, directly demonstrating the claimed visual result. (f7a450a675a5)
• Repository handling signal: The item carries the protected maintainer label, which requires explicit maintainer handling and rules out automated close cleanup. (f7a450a675a5)
• Current contributor history: Repository activity identifies steipete as a recurring contributor to current main, supporting routing to them for the intended UI direction, although the available history did not establish sole ownership of this CSS area. (ui/src/styles/layout.css:1982, f7a450a675a5)

Likely related people:

• steipete: Authored this focused roster styling change and appears repeatedly in current repository activity; ownership of the existing roster surface is otherwise not established by the available history. (role: recent core contributor and current UI-direction contact; confidence: low; commits: f7a450a675a5; files: ui/src/styles/layout.css)

• 🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
• 🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
• 🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
• 🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
• 🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
• 🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
• 🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.
