721 rows. A percentage measures this target’s own surface; it doesn’t rank targets against each other (why).

Info · 2

info TST1204 tokens/semantic.tokens.json:6:9

semantic.color.primary.solid has no authored value for color-scheme=dark — the light-mode value carries over unchanged, and so does its whole derived grid

↳ Author semantic.color.primary.solid for color-scheme=dark if this role should differ in that mode. This is default behavior — nothing is broken.
info TST1114

4 option tokens are never referenced: option.color.blue.500, option.color.blue.700, option.color.gray.100, …

↳ Alias them from a semantic or component token, or delete them. Nothing reads an option token directly.

Same shape as AL2's size-ladder deferral; Bootstrap defaults keptmeaning `type.display-ladder`
`$spacer` Trace it from the project: `npx transtyle explain --variable '$spacer' --target bootstrap`	native	not given	`semantic.space.4`

`$grid-breakpoints/$container-max-widths` Trace it from the project: `npx transtyle explain --variable '$grid-breakpoints/$container-max-widths' --target bootstrap`	unsupported	not given	`—`	`semantic.breakpoint.*` ships (6 rungs), but only `md` (768px) agrees: Bootstrap's sm/lg/xl/xxl are 576/992/1200/1400 against the catalog's 640/1024/1280/1536, and its `xs` is `0` — the unqueried mobile-first base, not a boundary at all, where the catalog's is 480px. Rebinding would move every responsive boundary in the framework: a behavioral change, not a theming one. `$container-max-widths` has no IR counterpart at all. Bootstrap defaults keptmeaning `breakpoint.ladder`
`motion ($transition-*)`	dropped	not given	`—`	the global $transition-base/-fade stay Bootstrap defaults; per-component transitions are driven — see the component-tier rows
`$component-active-color` Trace it from the project: `npx transtyle explain --variable '$component-active-color' --target bootstrap`	derived	not given	`semantic.color.primary.on-solid`	review pickup (AL1.2 findings): Bootstrap hardcodes $white; $component-active-bg already chains from $primary

`$btn-close-opacity` Trace it from the project: `npx transtyle explain --variable '$btn-close-opacity' --target bootstrap`	unsupported	not given	`—`	opacity value with no shared meaning: AL2 promoted `semantic.opacity.disabled` (the one both reference targets needed) but this slot is a different concept — a veil strength, a shimmer range, or a glyph-specific alpha. Growth signal only if a second target needs the identical one.meaning `opacity.component`
`$btn-close-hover-opacity` Trace it from the project: `npx transtyle explain --variable '$btn-close-hover-opacity' --target bootstrap`	unsupported	not given	`—`	opacity value with no shared meaning: AL2 promoted `semantic.opacity.disabled` (the one both reference targets needed) but this slot is a different concept — a veil strength, a shimmer range, or a glyph-specific alpha. Growth signal only if a second target needs the identical one.meaning `opacity.component`
`$btn-close-focus-opacity` Trace it from the project: `npx transtyle explain --variable '$btn-close-focus-opacity' --target bootstrap`	unsupported	not given	`—`	opacity value with no shared meaning: AL2 promoted `semantic.opacity.disabled` (the one both reference targets needed) but this slot is a different concept — a veil strength, a shimmer range, or a glyph-specific alpha. Growth signal only if a second target needs the identical one.meaning `opacity.component`
`$btn-close-disabled-opacity` Trace it from the project: `npx transtyle explain --variable '$btn-close-disabled-opacity' --target bootstrap`	unsupported	not given	`—`	the same concept as `semantic.opacity.disabled`, but not bindable to it: Bootstrap composes this against the glyph's own resting alpha ($btn-close-opacity: .5), so writing the catalog value (0.6) here would make the disabled close button MORE visible than the enabled one. Needs a compositional recipe (catalog factor x the target's resting alpha) the cross-walk has no form for yet — a real AL2-style growth signal, unlike the other -opacity rows in this family.meaning `opacity.compositional`
`$btn-close-filter` Trace it from the project: `npx transtyle explain --variable '$btn-close-filter' --target bootstrap`	dropped	not given	`—`	Bootstrap cascade no-op marker (null/inherit/transparent/currentcolor) left untouched — overriding would change inheritance behavior, not theme values

`(mode:contrast)`	approximated	not given	`—`	the CSS path (bootstrap-theme.css) carries the contrast blocks; the Sass path compiles the standard-contrast values, so load bootstrap-theme.css after a Sass build to get them
