Priority fixes for rosebikes.de

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   Modern image formats in use

   Observed: The homepage had 20 images and none used WebP or AVIF.

   Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   On Nuxt: Nuxt Image can output WebP and AVIF.

   47% of E-Commerce & Marketplaces peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
