/* Design plan
   Subject: a developer/IT-admin-facing API that converts proprietary dental
   x-ray formats (Dexis, Eaglesoft) into JPEG for dental practices.
   Color: cool clinical off-white ground, near-black cool ink, deep teal
   accent (trust/medical, distinct from generic SaaS blue), dark "film
   negative" panels for code -- literalizing the subject (x-ray film) rather
   than decorating it.
   Type: Archivo (display, structural/confident) + Source Sans 3 (body,
   quiet and readable) + IBM Plex Mono (code -- the API itself is the
   content here, not an afterthought).
   Layout: slim persistent header (wordmark + Docs/Sign up), generous
   single-column content, sticky in-page nav on the docs page only. */
