/* post-light.css -- the blog post template, rebuilt from the measured
   big-company design system. Lloyd, 2026-09-21 05:50: "Copy what the big
   companies do exactly."

   Every number below is measured, not taste. Sources:
     chief-home/out/apple-site-design-lessons/  (18 Apple pages, 8 OpenAI,
       4 Meta, at 390x844 and 1440x900: summary.json, font-scale.json,
       colour-pairs.json)
     chief-home/out/anthropic-site-design-lessons/LESSONS.md

   What was measured, and what it set here:
     body colour on ground   rgb(29,29,31) on rgb(245,245,247)  --ink / --ground
     secondary text          rgb(110,110,115)                   --ink-2
     body size               17px (apple body_px median)        --t-body
     small print             12-14px (top of the apple font scale)
     h1                      40px phone / 64px desktop          about 2.9x body
     h2 max                  32px phone / 48px desktop
     h1 length               2 words median; ours carries the search query
     first screen            23-25 words median
     section                 54-62 words median on a phone
     CTA label               2 words median
     autoplay                0 on every page measured

   Scoped to body.post-light so the rest of getgodmode.dev is untouched. Copy
   the design system, never anyone's logo, image or sentence. */
