Hovering, focusing or touching a link to /projects/ now gets its cover images ready before the click.
imagesrcset/imagesizes, so the browser picks the same size the page will use. Skipped when Data Saver is on.src/lib/projects.ts, shared by the page and the warmup.Verified in Chrome and WebKit at 1280@2x and 390@3x: hover fetches exactly the variant the page then displays (640w on desktop, 1280w on phones), nothing before hover, no console errors. Check, build and tests pass.
