/*
 * PWA install + notification prompts.
 *
 * Plain CSS rather than a scss/ partial, and loaded separately (like
 * skeleton.css): these elements only ever exist when pwa.js injects them, so
 * folding them into index.min.css would add bytes to every page for a widget
 * most page views never render.
 *
 * Everything is namespaced under .lb-pwa- and uses its own tokens, so nothing
 * here depends on Bootstrap being present or on the site's SCSS variables.
