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").
Distance confidence
- Every distance surface takes the figure AND its "Approx." marker from one
FuelStore.stationDistanceDisplay call (station rows, detail sheet, widget,
Live Activity, watch, Siri), so a surface can never mark one figure approximate
while showing a routed one. Radius filters and Closest ordering test that same
displayed distance, so no row can read a distance outside the radius that
filtered it (the reported "14.6 mi inside a 10-mile list").
Accurate distances (Settings -> Distances, default off)
- Off: the browse layer serves the straight line, marked Approx., for every row,
so two installs agree to the metre and the app makes no route requests at all.
- On: routed distances for the whole search area, unmarked, served only from a
COMPLETE set anchored within 600 m — a partial fill reverts every row at once
rather than mixing road and straight-line bases.
- Best Value maths sits deliberately outside the toggle: it keeps using measured
road routes and its own confidence marking, so money figures never move with
the switch.
- Fills run only while the toggle is on and the app is frontmost; capacity raised
to 600 stations per pass; completeness tolerates pins Apple Maps has no route
for, which otherwise left an area permanently incomplete and the whole list
stuck on estimates.
Performance (the reported slowdown switching to Closest / launching with it)
- FuelStore.accurateDistancesEnabled was a UserDefaults(suiteName:) read per
call: a synchronous cfprefsd round-trip measured at ~1.9 us, ~200k calls per
Closest sort. Memoised, with the setter keeping it in step.
- Both keyed sorts decorate their keys — one distance per station, carried as an
index instead of copying whole stations into the decorated array — and the
comparison baseline plus per-station journeys now come from ONE pass instead of
two full scans per tab. The Stations tab also reuses its single sorted list for
the count and the TOP badge instead of sorting the country three times.
- Measured on iPhone SE (7,914-station Closest pool): sort 36.6 ms -> 17.1 ms per
list, Cheapest 6 ms, Best Value 11 ms.
- DEBUG probes: FB_PERF list timing, FB_PERF_BENCH toggle-read benchmark, and
FB_DIST_FOCUS now reports the served value, marker and mode (and re-prints when
a fill lands). FB_ACCURATE_DISTANCES / FB_SORT_MODE env forms for devices, where
devicectl eats a leading-dash argument.
Tests: 198, 0 failures. Device and simulator Debug builds green.
