feat: glass and portal subpaths, and capped chart axis labels

[danestves]

Two fixes an app was carrying as a local patch against 0.112.0.

Glass and Portal had no subpath. An app importing by subpath had to fall back to the root entry for useGlassMaterial and PortalHost/PortalProvider, which loads every component. Both modules are already root-public, so they are added as leaves in generate-subpath-exports.mjs and the exports map is regenerated. The subpath test and the README's leaf list are updated to match.

Axis labels outgrew their gutters at large text sizes. Axis labels sit in fixed-width gutters at fixed steps, so at the accessibility text sizes they overlapped each other or clipped. A shared CHART_AXIS_MAX_FONT_SCALE (1.353, iOS's largest size before the accessibility range) in primitives/chart-accessibility.ts now caps every axis label in all 13 charts: area, bar, bubble, bump, candlestick, heatmap, line, live-line, mirror-area, plot, pyramid, scatter and waterfall. Screen readers still get the values through each chart's accessibility data. Tooltips, headers and legends are untouched.

Verified with typecheck, build, npm test, docs:generate (no drift) and verify:package. Not checked on a device.

Summary by CodeRabbit

• Accessibility
  • Chart axis labels across chart types now support system text scaling up to a consistent maximum.
  • Heatmap axis sizing adjusts with text scale, and weekday labels remain on one line.
• Package Exports
  • Added public entry points for the Glass and Portal primitives.
• Documentation
  • Clarified that heatmap Y-axis width defaults to 26 and can expand with system text size.

📝 Walkthrough

Chart axis labels now use a shared maximum font-scale value. The heatmap chart adjusts axis dimensions for system font scale. The package also adds glass and portal primitive subpath exports and updates the generated export list, tests, and README.

Changes: Chart axis font scaling

Layer / File(s)	Summary
Shared axis font-scale value packages/panelui/src/primitives/chart-accessibility.ts, apps/docs/public/r/chart-accessibility.json	Adds CHART_AXIS_MAX_FONT_SCALE with a value of 1.353.
Chart component axis labels packages/panelui/src/components/*-chart/index.tsx, packages/panelui/src/components/plot/index.tsx	Chart axis labels use the shared value as maxFontSizeMultiplier.
Heatmap axis sizing packages/panelui/src/components/heatmap-chart/index.tsx, apps/docs/public/r/heatmap-chart.json, apps/docs/content/docs/charts/heatmap-chart.mdx, apps/docs/public/skills/panelui/components/heatmap-chart.md, skills/panelui/components/heatmap-chart.md	The heatmap chart scales axis dimensions with system font scale. Its default y-axis width expands with system text size, and the documentation describes this behavior.
Chart registry sources apps/docs/public/r/*-chart.json, apps/docs/public/r/index.json	Registry chart sources apply the axis-label limit. The live-line-chart registry entry adds the chart-accessibility dependency.

Primitive subpath exports

Layer / File(s)	Summary
Glass and portal subpath exports packages/panelui/package.json, packages/panelui/scripts/generate-subpath-exports.mjs, packages/panelui/test/subpath-exports.test.mjs, packages/panelui/README.md	Adds glass and portal to package exports, generated subpaths, export tests, and the documented primitive subpaths.

Merge Risk: ⚪ Minimal · up to 3afc0

The chart-axis changes apply a consistent cap while preserving accessibility data, and the Glass and Portal exports map to package files produced and included by the build. No material merge-blocking issue was identified.

Merged — thanks @danestves, and welcome back! Really good to see you contributing again.

Both fixes checked out on the simulator: the axis labels now fit at the largest text sizes, and nothing moves at the default size. The heatmap's gutters were tighter than the cap allowed (weekdays wrapped and the months ran into the cells), so I pushed a small follow-up that grows them with the labels. These will go out in the next release.
