Spacing does not exist as a token in lib/tokens/. Components currently use
inline magic numbers (e.g., EdgeInsets.symmetric(horizontal: 12, vertical: 8)).
Tokenizing spacing requires a separate design session to decide:
- Scale system — 4-multiple? T-shirt? Numeric? Polaris-style?
- Authoring —
lib/tokens/spacing.dart with the chosen scale. - Refactor — replace inline literals across
lib/components/*.dart and
lib/pages/*.dart.
See PRD 05 §6 末 + §8 phase-deferred table for the framing. This is intentionally
out of Phase B–E migration scope.
