/**
|
|
* Read the device's WeChat font-size scale and compensate the ring number
|
|
* so it never overflows the fixed circular clip on real devices.
|
|
*
|
|
* WeChat auto-applies `fontSizeScaleFactor` to ALL text (including rpx font
|
|
* sizes) but leaves rpx box dimensions untouched. A user who bumps up the
|
|
* system font therefore sees enlarged text inside a non-enlarged ring.
|
|
*
|
|
* CRITICAL asymmetry: the DevTools simulator reports the SAME
|
|
* `fontSizeScaleFactor` as a real device (the user's actual WeChat setting)
|
|
* but does NOT actually scale rendered text. So if we compensate there, the
|
|
* number ends up too small in the simulator. We therefore SKIP the
|
|
* compensation under DevTools (host.env === 'devtools') and keep the design
|
|
* size — matching what the simulator renders literally.
|
|
*
|
|
* On real devices, dividing our design size by the factor cancels the
|
|
* auto-scale, keeping the number a constant 84rpx-equivalent everywhere.
|
|
* Bounded so a bad reading can only ever make the number smaller (safe),
|
|
* never larger (overflow).
