Severity: low
Category: security
Location: templates/index.html:3 (and assets/income/summary)

Problem

Chart.js is loaded from jsDelivr with no integrity hash; a compromised/overwritten CDN asset would run with access to all on-page budget data.

Suggested fix

Add integrity="sha384-..." crossorigin="anonymous", or self-host under static/.
