forgepulse: an award badge for repositories in the top 10 of both rankings

forgepulse publishes two rankings of the same fleet — human attention, built from unique views, external referrers and new stars and forks, and raw clone volume — and they rarely agree, so a repository that reaches the top ten of both now carries an award badge beside its rank, in either view (55028f2). The condition lives in web/src/lib/rank.ts as inBothTopN, which is true only when the attention rank exists and both ranks are 10 or better; the badge is styled in styles.css and the rule is covered by rank.test.ts.
