One adaptive tone palette and one shape rule now drive every capsule on
Stations, Favourites, the detail sheet and the Key.
- CapsuleTone: the light/dark palette pairs in one place, resolved through a
UIColor dynamic provider so a List row that re-renders without rebuilding
its body still follows an appearance switch. Every pair clears 4.5:1
foreground-on-background in both appearances (4.96-6.72:1).
- AdaptiveCapsule: capsule at one drawn line, rounded rect at two or more,
radius 8 -> 10, measuring content before padding so insets cannot inflate
the line count.
- Listing verdict capsules move from white-on-muted-solid to the tinted
palette, so Saves, Break even, Costs and Closest station read the same in
the rows and in the detail sheet.
- Best Value is purple, not green: green stays reserved for a financial
saving, which is what the Saves capsule beside it means.
- Price dots standardise to 12pt in the app (widget keeps its own 6pt dot;
PriceRatingDot now takes a diameter so the difference is deliberate).
- Station labels are sentence case with their recommended symbols (medal, tag,
location.north.fill, trophy) and StationLabelKind replaces the Key's
string-literal dispatch, so renaming a label can no longer drop a row.
- Key says "Costs", matching the capsule's own headline (was "Costs more").
