/* ebill admin panel — external stylesheet.
 *
 * An external file, and that is a security control rather than a tidiness choice:
 * the CSP is `style-src 'self'` with no 'unsafe-inline', so an inline `<style>`
 * block or a `style="..."` attribute would be REFUSED by the browser. Styling
 * therefore lives here or nowhere. The same applies to app.js — `script-src
 * 'self'`, no inline handlers, no `onclick`.
