/* LocalFit: one stylesheet. White and black with silver accents; flat colour only.
   Type: Newsreader (display serif), IBM Plex Sans (UI), IBM Plex Mono (IDs, quants), self-hosted.
   Light by default; dark via prefers-color-scheme or the header toggle ([data-theme] wins both ways).
   Memory-meter steps are a validated one-hue (cool silver) ordinal ramp per theme. */
