PAINTER — an MS-Paint-style drawing surface as a video SOURCE. The card is a tiny Windows-95 Paint: a tool grid (PENCIL = hard 1px, BRUSH = round sized stroke, ERASER = paints the background colour, LINE, RECT, ELLIPSE, FILL = flood fill, EYEDROPPER = pick a colour off the canvas, TEXT = stamp a string), the classic 28-colour Win95 palette (left-click a swatch = FOREGROUND, right-click = BACKGROUND), a SIZE slider (brush/line width 1..48), a FILL toggle (outline vs background-filled rect/ellipse), and an engine-resolution drawing canvas. Whatever you paint is the single video OUTPUT in real time: the card binds its live canvas to the module once and the engine uploads that canvas every frame (a 1:1 mapping — the canvas IS the frame). MODEL: the drawing is a Y.Doc-synced ordered op log (node.data.ops) — each committed stroke / shape / fill / text appends one PaintOp; on mount and on any remote edit the card REPLAYS the log onto the canvas (deterministic, pure painter-draw.ts), so every rack-mate paints the same picture. Tool / colour / brush-size are LOCAL per-collaborator (only the drawing syncs). UNDO pops the last op; CLEAR empties the log to a blank white page. IO — Inputs: none (a pure source). Output: out (video) — the painted canvas at the engine output resolution. The OUT port lives in the card's yellow drill-down PATCH PANEL (no raw side jacks, #767 standard). A freshly-spawned node renders a blank WHITE page (MS-Paint's default), so it is never a dead black frame. USAGE: paint a logo / title card / doodle and route OUT into a mixer / keyer / effect / OUTPUT; collaborate on one canvas in a shared rack.

painter is an interactive MS-Paint-style drawing SURFACE that acts as a pure video SOURCE — there is no video input. The card is a tiny Windows-95 Paint: a 9-tool palette (pencil, brush, eraser, fill, pick/eyedropper, line, rect, ellipse, text), the classic 28-colour Win95 swatch grid (2 rows x 14), a SIZE slider, a FILL toggle, and an engine-resolution drawing canvas. The tools work the MS-Paint way — pencil draws a hard 1px stroke; brush/line/rect/ellipse draw at the SIZE width; FILL toggles a filled vs outlined interior for rect/ellipse; fill flood-fills under the click with the FOREGROUND colour; pick (eyedropper) samples a pixel's colour; and text stamps the typed string. Left-click a swatch sets the FOREGROUND (strokes/text/fill), right-click sets the BACKGROUND (eraser + filled-shape interior); tool and colour choices stay LOCAL per collaborator. UNDO removes the last committed op and CLEAR empties the canvas back to a blank white page. Whatever you paint appears in real time on the single video output, 1:1 — the card binds its live canvas to the module once and the engine uploads + blits it into the output FBO every frame (1024x768 in 4:3, 1366x768 in 16:9). Until you draw anything the output is a flat opaque WHITE page (MS-Paint's default blank page), never a dead black frame — the shader returns solid white when no canvas is bound. The drawing is stored as a Y.Doc-synced ordered op log (node.data.ops): each committed stroke/shape/fill/text appends one PaintOp and on mount/remote-edit the card deterministically replays the log, so every collaborator sees the same picture. The card's drawing/preview canvas is resizable (it flex-fills the space between the toolbar and palette and is the actual video output); resizing only scales the on-card display — the output stays at engine resolution. Usage: spawn it, pick a tool and colour, draw, and patch OUT (on the yellow drill-down patch panel) into any video destination (mixer, keyer, effect, output) to use your sketch as a live source or hand-drawn matte.
