One-shot prettier pass so the new format:check gate starts from a clean baseline. Formatting only — no behaviour change. Generator-owned and vendored artifacts stay untouched via .prettierignore.

* good for some metrics (mood, HRV, steps), bad for others (resting HR,
|
|
* weight, body fat), and value-judgement-free for the rest.
