/*
 * OBD Dynamics App — front-end install prompt.
 *
 * Scoped entirely under .oba-install so it cannot leak into the theme, and
 * driven by --oba-* custom properties that the plugin prints inline from the
 * site's own brand colour. It deliberately does NOT read the theme's variables:
 * half the themes in this estate do not declare them, and a missing --brand
 * used to leave the install button's label the same colour as its background.
 *
 * The card is a light surface by default and follows the device to dark, so it
 * sits well on both a white page and a dark one.
