 * InvoiceSnap. Tokens first; components only use tokens.
 * Look: a bookkeeper's ledger, not an app template. Paper and ink, serif headings like a printed
 * invoice, thin rules instead of boxes, square-ish corners, no soft shadows, statuses as text with
 * a dot, icons only where they help someone find the button. No blue anywhere, grays included.
