New Features

• Geist-style code diffs: ui.code and <code> can mark added and removed logical lines with theme-aware full-row washes, renderer-owned +/- markers, optional line numbers, and unchanged syntax-highlighted clipboard source.

Improvements

• Verified Zig setup: repository and generated CI workflows now install Zig with vercel-labs/setup-zig, including signed archive and checksum verification.

Bug Fixes

• Theme-accurate disabled buttons: disabled buttons now keep shadcn's knockout label treatment in the default theme and use Geist's gray-100/gray-700 swap, gray-400 edge, and distinct half-opacity tertiary register in the Geist theme.
• Canonical documentation routes: documentation now lives under /docs/, with permanent redirects from every previous URL, explicit canonical metadata, .md siblings, and a generated llms.txt that stays aligned with each page's canonical MDX source.
• Geist primary tabs match the design system: tab strips now use the reference 50px row, full-width bottom rail, content-hugging 14px triggers, 24px spacing, and 16px icon treatment without changing default-theme pill tabs; the GPU component gallery now pairs a compact theme picker with a scrollable component tree and focused specimen views.
• Quiet Windows subprocesses: Effects.spawn no longer opens or flashes a console window when a GUI or tray app launches a console-subsystem helper such as node.exe; interactive terminal children remain on the separate PTY API.
• Responsive Windows GPU surfaces: Windows now renders retained binary canvas packets with Direct2D and DirectWrite, applies dirty-region patches (including edge-safe GPU-resident backdrop blur), and limits RGBA-to-BGRA conversion and invalidation to dirty pixels when software fallback is required.
• Exact Windows packet text and chrome: Packet rendering now refuses when the bundled/custom font path cannot preserve engine-planned metrics, preserves explicitly positioned glyph runs, prevents system glyph substitution, and samples a covered, changed hidden-titlebar pixel for native caption contrast.
• Truthful GPU backend types: TypeScript creation options now expose only portable backend requests while view and frame state can report the concrete Direct2D renderer; explicit software requests bypass packet encoding and image uploads and stay on the reference renderer and pixel presenter.
• Reliable registered-image replacement: Unregistering and then re-registering identical pixels now recreates the removed GPU resource instead of retaining a stale cache key and silently omitting the image.
