🔧 Bug fixes
- Xiaomi Home mode now matches the S400 firmware itself: @RX14 ran the original S400 Pro firmware under qemu and compared it with the Xiaomi Home mode on more than 30,000 input combinations, then fixed every difference in #478. Only 4 values in 30,411 still differ by 0.1, on exact rounding boundaries.
- Body age for children: under 18, body age was always shown as 18. It now uses the firmware's youth rule (real age ± 1 year), and the reference body fat for 11-year-old girls is fixed (20 %, not 25 %).
- Water and protein: the firmware forms protein first and gives the remainder to water. Values could differ from the app by 0.1, or by several points when protein reaches its 5 % floor.
- Lean mass, muscle and BMR: lean mass is now weight minus the rounded fat mass, as on the scale. Muscle could differ by 0.1 kg and BMR by up to 3 kcal.
- Bone: below 0.3 kg the firmware stores 0 kg.
- Body fat floor: in Xiaomi Home mode, a body fat below 5 % was shown as 5 % instead of the firmware's 3 % floor.
