/* theme.css — canonical design tokens for jdbb studio ("Terminal Folio").
 *
 * This file is the ONE source of truth for color/type tokens. Pages link it
 * ahead of their page CSS; the legacy :root blocks in style.css / admin.html /
 * landing.html were removed in favor of this file.
 *
 * System rules (see docs/DESIGN-SYSTEM.md):
 *  - cardless ledger: hairline rules + whitespace + aligned columns, no boxes
 *  - zero border-radius, zero shadows, zero gradients
 *  - one filled accent button per page; all other actions are underlined links
 *  - tags are plain bracketed mono text, never pills
