The toggle palette cascade (palette-track / palette-hover / palette-border
declarations in TSC) referenced --toggle-{X}-track, --toggle-{X}-hover,
--toggle-{X}-border for X in {primary, neutral, secondary, affirm, risk,
threat} — but the recipe only declared 5 forwarders per color (element /
solid / solid-hover / text / contrast). The 3 missing slots × 6 colors =
18 unresolved tokens made --toggle-palette-{track,hover,border} resolve
to empty for any non-neutral color (the host default DID declare them).
Visible effect, only when a non-neutral color was active:
- ghost-on-bg = var(--toggle-palette-track) → empty → transparent fallback
- ghost-on-border = color-mix(... palette-border ...) → invalid →
property dropped, border falls through to base layer
- outline-on-bg = color-mix(... palette-element ...) was the one that
worked because palette-element forwarders DID exist for all 6 colors
Surfaced today while verifying the TSC v2.2 toggle-group color cascade
fix in the browser. The toggle-group composition correctly overrode
--toggle-palette-* on items, but the empty track/hover/border slots
collapsed ghost-state styling downstream.
Verified with browser probe (preview_inspect):
- ghost + affirm: paletteTrack #0d1514, paletteHover #023b37,
paletteBorder #145750 (was "")
- ghost + threat: paletteTrack #191111, paletteHover #500f1c,
paletteBorder #72232d (was "")
- outline + primary: paletteTrack #18111b, paletteHover #3d224e,
paletteBorder #54346b (was "")
Tests: 100/100 pass in src/uix/eidos. Recipe contract guard accepts
the new forwarders (kebab-case, valid var() values).
