Checkbox

1// Base UI base checkbox — runs on the @octanejs/base-ui `Checkbox` primitive.
2//
3// THE CONDITIONAL UTILITIES ARE ADAPTED, NOT COPIED, and the reason is structural rather than
4// stylistic. Base UI's Checkbox.Root renders a `<span role="checkbox">` — verified by rendering
5// it, not assumed — with a visually-hidden native `<input>` alongside it for form submission.
6// A `<span>` is never `:disabled`, so Tailwind's `disabled:` variant (which compiles to the
7// `:disabled` pseudo-class) can NEVER match. The primitive publishes `data-disabled` instead:
8//
9//   radix base:   `disabled:opacity-50`        -> matches, Root is a real button
10//   base-ui base: `data-disabled:opacity-50`   <- what this file uses
11//
12// `data-checked:` needs no change — the radix base already uses that exact form, and Base UI
13// emits `data-checked`/`data-unchecked` too. `focus-visible:` also stays: the span carries
14// tabindex, so the native pseudo-class applies.
15//
16// UNVERIFIED PROVENANCE: the non-conditional utilities are taken from this package's radix base
17// rather than transcribed from upstream's Base UI source.
