* feat(mobile): add SureSpacing + SureTypography scale tokens
Introduce hand-authored spacing and type-scale constants mirroring the
Tailwind defaults the web design system relies on, so widgets reference a
named step instead of a raw numeric EdgeInsets/SizedBox/fontSize.
- SureSpacing: xs..huge mapping to Tailwind space-1..space-8 (4..32px).
- SureTypography: xs..xxl mapping to Tailwind text-xs..text-2xl font sizes.
Both are hand-written rather than generated from sure.tokens.json because
spacing and the type ramp come from Tailwind's built-in scale, not the
canonical token file (consistent with the tracker's guidance).
Adopt them in the existing primitives (card padding, button metrics +
gap, chip/segmented/list-group gaps and padding, text-field padding +
label gap). All migrations are value-preserving — each token equals the
literal it replaces — so there is no layout change; off-scale one-offs
(control heights, hairlines, deliberate 14px field padding) stay literal.
flutter analyze: no new issues; full suite (166) green.
* docs(mobile): note off-scale SureChip inset; expose SureTypography line heights
Address review feedback (jjmata):
- SureChip: add an inline comment explaining the horizontal:14 content inset is
deliberately off the SureSpacing scale (between lg=12 and xl=16) — a tuned
FilterChip-parity dimension, not a spacing step — so it isn't "fixed" to a
token later.
- SureTypography: expose the paired line heights (xsLineHeight … xxlLineHeight,
logical px matching the Tailwind text-* defaults) that were previously only in
doc comments, with a note on deriving Flutter's TextStyle.height multiplier
(lineHeight / fontSize). No behavior change.
* feat(mobile): add SureChip primitive and migrate the currency filter
Adds SureChip, the filter-chip primitive following SureTextField in the mobile
design-system sequence: a tokenized selectable pill resolving from the active
SureColors palette — a bordered transparent pill when unselected and a filled
neutral (buttonPrimary + inverse label) pill when selected — replacing the
Material FilterChip primaryContainer tint + blue primary border. Includes
selected-state semantics (announced as a button only when interactive), a 44px
min tap target, and single-line ellipsised labels.
Migrates the currency filter off Material FilterChip as proof (selection logic
preserved). The segmented control will follow as a separate PR.
Part of #2235.
* fix(mobile): normalize stale codes in currency filter All detection
Length-based All detection could misfire when selectedCurrencies holds
stale codes no longer in availableCurrencies. Intersect with the
available set before comparing, and require containsAll before emitting
the empty (All) selection. Addresses CodeRabbit review.
