/* Autonomics AI services site, v3 (2026-11-04).
   System, per design-guide/anti-ai-slop.md:
   - Type: Archivo (variable width + weight) for headlines and labels; Source Serif 4 for reading text. OFL, self-hosted.
   - Colour: docket paper, carbon ink, one vermilion signal. No blue, no gradients except the perforation holes.
   - One signature move: the docket (paper slip, heavy top rule, punched left edge) for forms and price sheets.
   - Times in the margin ("7:42 pm") as the second motif. No uppercase eyebrows, no card grids, no scroll motion. */
