   Mission-control aesthetic: dense, dark-friendly, legible, fast.
   Anti-slop floor per memory/reference_site_design_standards.md:
   no purple/violet, no gradients-as-decoration, no glassmorphism,
   no fabricated numbers (placeholders always read "—" or a note).
   Fonts are system-stack only — no external font CDN (speed + no
