   Fire by day, water by night. Light mode = fire (warm, orange). Dark mode =
   water (charcoal + electric blue). The two accents trade places with the
   sun/moon toggle, mirroring the app icon: a fire arc resolving into a blue
   heart-rate pulse. Self-contained: system fonts only, no external requests. */
