"""The page loads its own script and styles by content hash (app 0.2.58, Vite build since 0.2.73).
|
|
|
|
After updating to 0.2.57, Safari showed an empty Screen settings panel: it kept a cached script from before
|
|
the update. Vite names every built file after a hash of its content and index.html asks for those names, so a
|
|
new version is always fetched and an old one is never combined with a new page.
