Generator (scripts/generate-htmx-css.ts): track `viaVariants` per slot so
slots that compose another component's variant system (e.g. ToggleGroupItem
via toggleVariants) inherit the referenced CVA's base + variant rules under
their own selector. Previously toggle-group-item's CSS contained only its
override classes, shipping with no padding/height/hover/active state.
Toggle (components/ui/toggle.tsx):
- data-[state=on] now uses bg-primary (orange) instead of bg-accent (grey),
matching every other "commit" affordance in the palette.
- Horizontal padding aligned with Button: px-4/px-3/px-6 per size, plus
has-[>svg]:px-* for icon-only toggles.
ToggleGroup (components/ui/toggle-group.tsx): drop min-w-0 flex-1 shrink-0
from the item override. Items now size to content instead of being clamped
into equal narrow columns where longer labels overflowed the bg box.
Showcase: add ToggleGroup section to the React page (component-matrix.tsx)
and 1:1 HTMX mirror (public/htmx.html) with a new JS bridge branch for
single/multi-select. compare-all.sh extended with the new section; 22/22
pass at ≥99.97%.
Docs: GAPS.md captures the generator gap, overflow root cause, color
rationale, and padding parity with before/after numbers.
