ZacharyZhang-NY e3038647c8 T25f Generative: data and prompts
DatasetViewer is tables::DataTable with row detail; the gallery pages
through a dataset and opens a sample whole. EmbeddingVisualizer scatters
points by group, flat or turned in three dimensions: lens.rs holds the
projection, where a turned view keeps the unit ball's scale and fits any
point past it at every turn. A drag or the arrow keys spin it, the
pointer names a point, and the legend hides a group. PromptPlayground
gives each {name} of a template a field, marks the blanks, and runs once
every value is in. PromptDiff shows word changes inline, a space parting
a word taken out from the word put in; PromptVersionHistory lists
versions to choose from and restore.

ChartLegend entries that toggle are Tab stops with the focus ring. Each
capture pass starts its page fresh, so dark runs the script from the same
start as light.
