/* Ericksonians design system.
 *
 * Rules baked in:
 *   - Lines not boxes. Hairline dividers + headings + whitespace structure
 *     content. NO card-style shadowed boxes.
 *   - Compact, ample whitespace. Generous padding around sections.
 *   - No tiny fonts (min 14px), no over-faded text (--ink-muted is readable).
 *   - Colored tags for status (active, expired, submitted, etc).
 *   - Highlighted hover state on every clickable element.
 *   - Mobile responsive throughout.
