Net-new data-visualisation family on the in-house, zero-dependency $libs/plots
engine (scales · ticks · curves · shapes, all original). Compositional <Chart>
frame (context-shared scales, responsive, cursor-following tooltip) + primitives
Grid/XAxis/YAxis/Line/Area/Bar/Scatter/Tooltip/Legend + presets Line/Area/Bar/
Scatter/Sparkline (line + bars) + standalone Pie/Radar/BarList/BarSegment, each
with a themed hover tooltip. Themed via --chart-* recipe tokens + global colour
tokens; locale via eidos.format/langs; morfo `chart` (scope: eidos, role=img).
Point scales span edge-to-edge. Per-chart demos under web/routes/uix/components.
Roadmap + MUI X Charts comparison in components/chart/IMPROVEMENTS.md.
Note: recipes/base.ts + generated/base.css are shared files; this commit
unavoidably carries the (inert) metrics recipe block that co-lives there.
