/* Year 2092 design tokens
   Foundation = the LXXXIV site kit (reference/lxxxiv-site-reference.html).
   Layer = the Year 2092 collateral accent (rate-card.html, sample report).
   Light-first, like the parent site. If a dark theme is added, follow the
   collateral's dark values and keep every color routed through these tokens. */

/* Usage rules
   - Body text is --ink on --paper or --card; never grey below 14px.
   - Brass is the Year 2092 accent; slate remains for links and structure.
     Spend brass sparingly: eyebrows, key rules, the primary CTA.
   - Charcoal fields host white type and --on-dark-2 secondary only.
   - All numbers, NSNs, and prices set in --mono with tabular numerals.
   - AA contrast is a floor, not a goal; check every new pairing. */
