Alternative food units (Phase 3a):
- serving_units table: шт, ст.л., ч.л., стакан, мл
- product_units junction: eggs linked to шт (60g)
- Unit selector chips in food modal after product selection
- Display "2 шт" instead of "120г" in food log when unit is set
- amount_g stays canonical, unit info is display metadata
Analytics (Phase 4):
- Stats section on Today screen with period selector (30d/90d)
- Weight trend chart (line, purple)
- Macros donut (protein/fat/carbs with kcal center text)
- Kcal balance bar chart (intake green vs expenditure red, includes BMR)
- Chart fullscreen + zoom support (reuses GPS chart patterns)
GPS improvements:
- Elevation smoothing: 5-point moving average + 1m dead zone
- Fixes inflated elevation gain (440m → ~70m for a real 70m route)
- Batch polyline update: poll loop suppresses per-point addLatLng,
calls onBatchUpdate to rebuild polyline from sorted points at once
- Eliminates visual jumps when app returns from background
Boot screen: removed verbose migration/GPS status labels,
shows "Загрузка..." only, updates text only during actual seed import
