Frontend & browser·Loading, assets and the critical path
you added a link tag to tell the browser about a file before anything on the page asked for it.
Resource hint
Also calledlink rel hint
A `link` declaration that tells the browser to do some network work early — resolve a hostname, open a connection, fetch a file, fetch a whole page. Hints are advisory: browsers apply their own heuristics and may ignore them under memory or network pressure. Used carelessly they compete with the resources that are actually critical, which makes a page slower by doing more work sooner.
