/*
 * LinkedIn Banner Maker: public landing + editor styles.
 *
 * Namespace: .lbm-*  (lives alongside .tl-* tools styles, same
 * pattern as .atsc-* for the resume checker).
 *
 * Built on the shared v2 design tokens (--rw-accent, --rw-text,
 * --rw-text-muted, --rw-bg, --rw-card-bg, --rw-border). No new
 * tokens, no gradients, no dark: variants; theming propagates
 * through the CSS variables automatically.
