Component parity with reference libraries

RavenRS aims to be more complete than the three reference libraries. This table tracks every component family they offer and where RavenRS stands. It is updated with each batch.

Legend: ✅ available · 🟡 partial (what is missing is noted) · ⬜ planned. Column S marks whether shadcn/ui ships it; D and T mark two commercial component suites for desktop and web.

Histogram				✅ `Histogram`: channels from ready-made bins, added up as light, linear or logarithmic, with marks at clipped ends
Ruler				✅ `Ruler`: horizontal or vertical, in the units of the caller, with a round step for the zoom, origin and marker; vertical numbers stack, since text does not rotate
Color wheel				✅ `ColorWheel`: hue and saturation on a disc that is computed once and shared, with arrow keys and Shift to keep the hue

Zoom and pan				✅ `ZoomPanView`: pinch, Cmd/Ctrl with the wheel, wheel and drag to move, double click, keys, inertia that respects reduced motion, limits. Content is an image or a closure: the runtime has no transform for a subtree
Minimap				✅ `Minimap`: a small copy with the rectangle of what is in view, by the same `ZoomView` as `ZoomPanView`, with drag and arrow keys
Composition grid				✅ `RuleOfThirdsGrid`: thirds, equal divisions, squares or the golden ratio, in a box or over a `ZoomPanView`, taking no input
Rubber band selection				✅ `RubberBand`: a rectangle drawn with a drag in `Binding`, selected on release, with the keyboard; costs no builds while dragged if nobody else reads it

Crop				✅ `CropOverlay`: on `TransformHandles` and the lines of `RuleOfThirdsGrid`, with a veil outside, fixed proportion and angle, returning rectangle and angle. The frame turns over a still picture, since the renderer has no transforms
Eyedropper				✅ `Eyedropper` and `EyedropperArea`: an armed button that takes the color of the point clicked, which the caller supplies with a closure or `EyedropperState::pick`; Esc disarms. It does not capture the screen, and `CursorIcon` has no dropper, so the cursor is the hand
Compare images				✅ `CompareView`: two images side by side or with a divider dragged or moved with the arrows, through `ImageQuad.uv`, with captions and an optional chosen side
Image lightbox				✅ `ImageLightbox`: a picture over the whole app with zoom by `ZoomPanView`, arrows, Esc, caption and counter, from `Labels`

Attachments of a message				✅ `AttachmentStrip`: icon or thumbnail, name that gives way, size, a menu for how to send it when there is a choice and a button to remove it; the app holds the list
Audio player				✅ `AudioPlayerButton`: play and stop over `SoundProvider::speak_clip`, progress by the clock, drawn without rebuilding, audio the app can deliver after the press, and a transcript to open or ask for. A new recording sends the old one back to rest. It has no seek, since the service does not report or change where it is
Bar over a multiple selection				✅ `SelectionBar`: the count from `Labels`, a way out by button or Esc, and actions over `Toolbar`, which go to a menu when they do not fit and wait for something chosen
Chat		✓	✓	✅ `Chat`, with marks and links by `RichText` and a photo, a document or a recording in the bubble by `ChatMedia`; `MovieChat` over training films
Choosing local AI models				✅ `ModelPicker`; `ravenrs_ai::ModelManager` offers only what fits
