What to build

Migrate SASS tokens in bpk-component-star-rating to CSS custom properties with SASS fallbacks.

Tokens with CSS vars:

• $bpk-status-warning-spot-day → var(--bpk-status-warning-spot, ...)
• $bpk-text-disabled-day → var(--bpk-text-disabled, ...)

Gaps — keep as bare SASS tokens:

• $bpk-duration-sm — animation duration
• $bpk-icon-size-sm — icon dimension
• $bpk-icon-size-lg — icon dimension
• $bpk-icon-size-xxxl — icon dimension

No themeAttributes.tsx needed — no --bpk-private-star-rating-* vars exist.

Acceptance criteria

• Covered tokens replaced with var(--css-var, tokens.$sass-fallback)
• Gap tokens left as bare SASS tokens with comments
• Storybook stories updated to include a dark mode story
• Existing tests pass unchanged
• No new CSS custom property names invented
