Drop the inset blue focus ring on text fields

[maxkongerskov]

What changed

Stop painting a sharp blue rectangle inside the composer (and other text fields) on click.

Chromium treats a pointer click on input / textarea / select as :focus-visible, so the global accent outline sat inset inside the rounded composer card. Those fields already have their own focus:border-*. Buttons still keep the keyboard :focus-visible ring.

Why

Clicking the composer drew a 2px accent rectangle with square corners inside the pill. It looked like a broken focus state, not a keyboard affordance.

How it was verified

Clicked the composer, settings fields, and model-picker search on macOS. No inset blue rectangle; Tab to a button still shows the accent ring.

Screenshots (UI changes)

Server/UI CSS only. The before state is a blue rectangle inside the composer pill on click; after, the pill border is unchanged.

Checklist

• pnpm typecheck and pnpm test pass locally
• Server behavior changes come with tests (see CONTRIBUTING.md → Tests)
• No dist-server/ edits (it's build output)
• macOS-only code is platform-gated; no shell: true / cmd.exe string-building
• No secrets in logs, responses, events, or argv

Summary by CodeRabbit

• Style
  • Updated focus styling for inputs, textareas, and select fields.
  • Removed the blue inset focus ring and outline offset from these form controls.

📝 Walkthrough

Walkthrough

The stylesheet changes focus styling for inputs, textareas, and selects. It removes the inset blue ring and resets the outline for both :focus and :focus-visible states.

Changes

Focus styling

Layer / File(s)	Summary
Text control focus reset src/styles.css	Focused and focus-visible inputs, textareas, and selects now use an outline reset instead of the previous inset focus ring. Button focus-visible styling remains controlled by the global rule.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to b5787

The CSS change can hide keyboard focus indicators on checkboxes, radios, sliders, file inputs, and other non-text controls, making keyboard navigation harder and potentially inaccessible. The selector should be limited to text fields before merging.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Scope the reset to text fields.

This selector matches every input, not only text inputs. Because it also matches :focus-visible, it removes the keyboard focus indicator from checkboxes, radios, range controls, file inputs, and other controls without the text-field focus:border-* replacement. Scope this rule to the text-field class or explicit text input types, and retain a visible :focus-visible style for other controls.
