/* Rich, Broke or Dead — Guided Planner ("The Almanac")
   Warm paper-and-ink editorial system. Fraunces display + Instrument Sans body.
   Chart colors are validated (see Plans/ notes): ordinal greens pass the
   light-surface ordinal checks; flow blue/terracotta/green pass categorical.

   Fonts are self-hosted (variable woff2, latin subset) so the page makes no
   requests to any third-party host — the tool is fully local by design. */
