 * Rebrand by changing the accent tokens below. Primary buttons use --btn-bg
 * (the logo's near-black #1e1e1e in light mode, near-white in dark mode).
 * The logo files are /static/logo.svg
 * (light backgrounds) and /static/logo-dark.svg (dark mode), set via
 * --logo-image below.
 *
 * Login hero image: to use a real photo instead of the default artwork, drop
 * the file in public/static/ (e.g. public/static/login-photo.jpg) and change
 * --hero-image to url("/static/login-photo.jpg"). It is shown with
 * background-size: cover, only on screens 900px and wider (never downloaded
 * on mobile), with a soft dark gradient at the bottom so any photo sits well on the page.
 * --hero-position controls which part of the photo stays visible when cropped.
