/**
|
|
* PWA installation state detection.
|
|
*
|
|
* 'ponomar-ever-installed' is a permanent marker (never removed): set when
|
|
* the app is installed, launched in standalone mode, or inherited from the
|
|
* legacy 'ponomar-installed' offer flag. Used to hide the Settings install
|
|
* button on browsers without getInstalledRelatedApps() (Firefox, Safari).
|
|
* Distinct from 'ponomar-installed', which only gates the first-launch
|
|
* offline-offer modal and is cleared on appinstalled for re-offer semantics.
