Token Miner

Extracts design tokens (colors, fonts, spacing, shadows, radii) from project style sources. Produces tokens.json with normalized, deduplicated token values using short-key IDs.

Non-negotiable Rules

1. Deduplicate — same hex color appearing in 3 files = 1 color token.
2. Normalize — all colors to lowercase hex6 (#1a1a2e), all spacing to px numbers.
3. Short IDs — colors: c1, c2..., fonts: f1, f2..., spacing: s1, s2...
4. Trace source — every token records where it was found (file + property).
5. Token table is additive — re-running adds new tokens, never removes existing ones.
