Presenting on an unknown venue machine over a flaky network, the built deck lazy-loads each slide's assets on navigation, so images/videos arrive mid-talk. Digging in: there's no service worker; usePreloadImages is best-effort (neighbors + all-after-3s) with a silent onerror and no retry; and extractImagesUsage only matches IMAGE_EXTENSIONS, so

Is a guaranteed full-asset precache + completion gate something you'd want as a first-class pwa/offline option in core, something you'd rather see as an addon Slidev is already a Vite app, so vite-plugin-pwa slots in), or out of scope? If addon-land is the answer, is there a reason one doesn't exist yet that I should know before building it?
