Casca 1.0.1 (2026-05-28)Link to section

Bundle restructure: the published artifacts are reorganized along two clean axes

• build (which components) and theme (the palette) - so the names tell the truth and the near-identical full-bundle duplication is gone. No component markup, class, selector, or value changed; this is purely how the CSS is packaged. Shipped as a patch because there are no external consumers yet (local consumers are updated in lockstep).

Breaking (artifact surface only)Link to section

• Themes are now overlays, not full bundles. The old casca-high-contrast.css / casca-minimal.css / casca-vibrant.css - each a full ~80 KB copy of every component that differed only by a ~1 KB palette - are replaced by tiny casca-theme-*.css overlays (~1 KB) you load over casca-core.css.
• casca-minimal → casca-theme-muted. Renamed to describe the palette (low-chroma/muted); it was never a smaller build.
• casca-dashboard.css is gone - its curated subset became the new core.
• casca-core.css is now the lean essentials (base + bar, line, area, pie/donut, progress/gauge, KPI stat cards, data table; ~9 KB gzip), no theme - no longer the full component set.
• New extension add-ons layer on core: casca-extended-charts.css (heatmap, scatter, waterfall, radar, candlestick) and casca-extended-controls.css (slot grid, range slider, toggle/switch/disclosure/filter).
• casca.css is unchanged in content - still the all-in-one (core + both extensions + default theme), byte-equivalent to 1.0.0's full bundle.
• Package exports changed: ./dashboard, ./minimal, ./high-contrast, ./vibrant removed; ./core, ./extended-charts, ./extended-controls, ./theme-default, ./theme-high-contrast, ./theme-muted, ./theme-vibrant are the new surface.

MigrationLink to section

• Full themed bundle → core + overlay: casca-high-contrast.css → casca-core.css + casca-theme-high-contrast.css (same for muted/vibrant).
• casca-dashboard.css → casca-core.css + casca-theme-default.css.
• Need a chart/control outside core? Add casca-extended-charts / casca-extended-controls, or just use the all-in-one casca.css.
