== Background
As of current the perceived performance is sluggish due to numerous reasons,
LCP on beta is 3.0 seconds, so over the general guidance of 2.5s. On testwiki (on my 1 list with 0 items) 3.9s.
- Loading of Vue.js to show anything below title.
- Collections list item thumbnails are delaying largest contentful paint as they are implemented as CSS background-images

==== Possible impacts (reminder)
First impressions
- Sluggish experience: Users perceive a website as slow or unresponsive when the main content takes longer than 3 seconds to load.
- Loss of trust: Visitors may assume the site is poorly optimized or unreliable, especially on mobile devices or slower connections.
- Reduced satisfaction: Studies show that users begin to lose patience after 2–3 seconds of waiting, which can create frustration.
Engagement impacts
- Higher bounce rates: Google data indicates that as page load time increases from 1s to 3s, the probability of bounce increases by ~32%. Beyond 3s, that risk grows sharply.
- Lower engagement: Slow LCP reduces the likelihood of scrolling, interacting, or exploring additional content.
- Interrupted task flow: Users who come to complete a specific action (like reading an article or making a purchase) are more likely to abandon it.
== Goal
Improve/speed up perceived loading time of ReadingLists
Early ideas are
- Exchanging Vue ProgressBar with CSS-only Progressbar
- Wider reaching were changing Card logic to be able to use <img> element for being discoverable in initial page load (also consider `fetchpriority=high`
