Widget reference

Load widgets from render.star:

load("render.star", "render")

Widget	Use
`Root`	Top-level frame, timing, and canvas boundary
`Box`	Size, background, and child alignment
`Row`	Horizontal layout
`Column`	Vertical layout
`Stack`	Layer children on the same canvas
`Padding`	Add explicit space around a child
`Text`	Draw one line with a bundled font
`WrappedText`	Wrap text within a width
`Image`	Decode and draw supported image bytes
`Circle`	Draw a filled circle
`Plot`	Draw a compact data series
`PieChart`	Draw weighted circular segments
`Marquee`	Scroll content that cannot fit
`Animation`	Treat children as sequential frames
`Sequence`	Compose timed child sequences

Many widgets expose size(); animated widgets can expose frame_count(). Colors accept CSS-style hex forms including #rgb, #rrggbb, #rgba, and #rrggbbaa.

The runtime repository generates the exhaustive attribute tables from the code. Until those generated tables are imported here, use niblet validation and the runtime source for exact signatures.
