Research direction

Start with the MarkdownEditor implementation and compare its toolbar markup, activeButton state, toolbarRefs, and keydown handler with the Radix Toolbar API. Run apps/web/tests/MarkdownEditor.test.tsx; done means the hand-rolled focus management is replaced while the existing single-tab-stop and Arrow/Home/End behavior still passes.

Description

enhancement

Context

PR #157 gave MarkdownEditor's formatting buttons role="toolbar", real names, and a hand-rolled roving tabindex (activeButton state + a keydown handler for Arrow/Home/End).

Problem

The roving tabindex is ~30 lines of bespoke focus management that duplicates what Radix's Toolbar primitive already does (roving focus, orientation, Home/End, RTL, and correct tabIndex bookkeeping). radix-ui is already a dependency of apps/web (radix-ui@^1.4.3) and exports Toolbar, so no new package is needed.

Proposal

Replace the <div role="toolbar"> + handleToolbarKeyDown + toolbarRefs/activeButton with Toolbar.Root / Toolbar.Button from radix-ui, keeping the aria-label="Formatting" and per-button names. apps/web/tests/MarkdownEditor.test.tsx already covers the single-tab-stop and Arrow/Home/End behaviour and should pass unchanged.

Deferred from plans/a11y-mechanical.md (PR #157).
