/* Skywriter marketing site — one hand-maintained stylesheet, no build step.
   Design source: the "Skywriter Front Page v2" canvas (sky palette, serif
   voice, contrail hero). Constraints this file lives under: the response CSP
   allows only this same-origin stylesheet (no inline styles, no scripts),
   and the pages reference no external origin — fonts are the system stack. */
