Highlights

• Adds the touch-input primitives needed to drive Aetna from a phone or tablet: PointerEvent ingest carries a modality tag, hover transitions are gated by contact for touch, touch scroll is synthesized through a gesture state machine, and a touch-press past 500ms emits a dedicated LongPress event alongside PointerCancel.
• Adds soft-keyboard support on the web host: tapping a text input synchronously focuses a hidden <input> from the pointerdown handler so iOS / Android summon the on-screen keyboard, with per-frame focus sync and a prevent_default guard so the browser's default focus-shift to the canvas no longer dismisses the keyboard one frame later.
• Adds responsive-layout primitives: BuildCx::with_viewport / viewport_below(...) for build-time phone-vs-desktop branching, min_width / max_width / min_height / max_height modifiers on El, and BuildCx::safe_area populated from VisualViewport on web so apps can inset around the on-screen keyboard.
• Reworks the showcase shell to switch from a sidebar to a phone-topbar layout below 700px, stacks input rows on phone, and tightens text and tile labels across pages so the common interactions fit a 360px viewport.
• Binds right-click on web (suppresses the browser context menu, routes PointerButton::Secondary through the runtime) and inflates focusable / selectable hit rects to a 44px floor so finger pads don't miss small icons.
• Fixes a soft-keyboard regression where a focused text input being clipped by a shrinking scroll viewport was clearing focus and dismissing the keyboard; focus now survives clip changes and only clears when the node truly leaves the tree.
• Internal: consolidates the paint, theme, and icons clusters into per-cluster directories; expands the math backend's TeX command coverage by ~85 operators and function names; stops the wheel from bubbling past block_pointer barriers.

47 commits since v0.3.1. Highlights:

Runtime hooks for embedding apps

• App::drain_focus_requests for programmatic focus by key (#20)
• App::drain_scroll_requests for programmatic scroll-to-row (#22)
• Link click event with per-run hit-test and a drain_link_opens hook; native host (winit-wgpu) opens URLs via the open crate, web host uses window.open
• Web target wires push_toasts so App::drain_toasts reaches the runtime

Text & scroll polish

• text_area now wraps content in a scroll viewport, clips overflow, and handles drag-select auto-scroll
• text_input adds horizontal caret-into-view + clip for overflow
• Generalized ScrollRequest::EnsureVisible drives caret-into-view in both editors
• scroll(...).pin_end() builder for chat-log stick-to-bottom behaviour
• Tooltips cache trigger text on UiTarget so virtual-list rows fire correctly

Performance & profiling

• Feature-gated tracing spans across aetna-core, aetna-wgpu, aetna-winit-wgpu; showcase --profile <path> writes a chrome://tracing JSON via tracing-chrome
• 10 sub-spans inside prepare::layout plus a layout::axis intrinsics/place split
• Thread-local LRU cache for shaped TextLayouts (avoids per-frame cosmic-text reshape)
• Paint-side LRU cache for atlas shape_runs
• Default fonts pre-rasterize printable ASCII at host startup
• FxHashMap for per-frame side maps; redundant assign_id walk skipped in prepare_layout
• Web target opts into a paint-only repaint path for shader-driven frames; runtime splits layout vs paint redraw deadlines

Rendering

• Vulkano backend threads sample_count through pipelines + render pass for MSAA; host + headless bins default to 4× MSAA
• Vector layer drops the analytic-AA fringe and relies on host MSAA for silhouette AA
• wgpu downlevels @interpolate(perspective, sample) when the adapter lacks MULTISAMPLED_SHADING
• draw_ops keeps scissor on image/surface/vector when an El is fully outside its inherited clip

Markdown

• Broader markdown rendering coverage for tables, footnotes, task lists, and more in aetna-markdown

Theming

• Drop the shadcn neutral surface; add Radix sand+amber and mauve+violet palettes
• Per-corner radius via a new Corners type
• Card inherits corner radii onto filled header/footer (with a matching lint for corner stackup)
• Per-edge Sides constructors; clip=true silences the Overflow lint

Lints

• Flag bare card([...]) whose children sit flush against panel edges
• Shape-specific advice for text overflowing its box
• Flag scrollbar-thumb overlap with focusables when a scroll has padding (#21)
• Flag dead .ellipsis() chain on Hug flex children (#19)

Showcase

• About landing page with two interactive teaser cards, sidebar diagnostics toggle, and link routing through the runtime hook
• Aetna badge icon in the About header and README banners
• Sidebar nav scroll padded so the thumb sits in a gutter
• Web target: tab title says Showcase; liquid-glass subsection skipped on wasm; HostDiagnostics overlay + sRGB view-format and ResizeObserver fixes

CI / deploy

• Pages workflow deploys the wasm showcase on every published release
