2 * Vizion Plus service worker (DECISIONS #252). Deliberately small: a news and live-TV site must
3 * never show yesterday's page, so nothing here caches stories, the guide or the stream.
4 *   · page loads go to the network; only when there is no connection does the offline page answer
5 *   · the offline page and the three files it needs are kept on the device
6 * 39667cae44 and ["/offline/","/wp-content/themes/vizionplus/assets/css/tokens.css?ver=1789943147","/wp-content/themes/vizionplus/assets/css/offline.css?ver=1789931778","/wp-content/themes/vizionplus/assets/pwa/offline.js?ver=1789931778","/wp-content/themes/vizionplus/assets/app/icon.svg"] are filled in by inc/pwa.php when it serves this file at /sw.js.
