v0.22.1

Fixed

• App no longer gets stuck on the "Oikos" splash screen when opened in a new tab. Two root causes addressed: (1) sw.js was not updated in v0.22.0, so the browser kept the old Service Worker and served stale cached files via Stale-While-Revalidate — cache versions are now bumped (shell v35, pages v30) to force reinstallation and fresh file delivery. (2) A fatal error in initI18n() (e.g. locale fetch failure while offline) left the splash screen visible forever — the router IIFE now catches such errors, hides the splash screen, and renders a recoverable error state.
• Service Worker now pre-caches /pages/recipes.js and /styles/recipes.css introduced in v0.22.0, enabling offline access to the Recipes page.
