   rpdtls.com — Stylesheet v5.0 (compact redesign, 2026-07-03)
   Editorial-industrial "commercial operating system" direction.
   Palette preserved: warm paper / graphite / restrained copper.
   Typography: Fraunces (variable, self-hosted, OFL) for display,
   IBM Plex Sans for body/nav, IBM Plex Mono for labels/system.
   No external font CDN (GDPR, Germany-based operation).
   Vanilla CSS, no build step, no frameworks.
