   EDITORIAL — "The Develop" long-form layer
   Guides read as the field manual: a sticky mono chapter rail,
   Fraunces chapter heads with counters, screenshots framed as
   film plates. Blog posts ride the same shell at lower intensity
   (their per-post inline styles are restyled by the legacy
   aliases in site.css). Loads after /site.css.
