   TYPE CHOICES (owner requirement: sturdy, long-reading body; no thin fonts)

   Body: Atkinson Hyperlegible Next (400/500/600/700 + italics)
     Designed by the Braille Institute for low-vision readers: large x-height, open apertures,
     generous spacing and real text weights. Its glyphs are deliberately disambiguated
     (I / l / 1, 0 / O, rn / m), which matters on a site full of acronyms, IP addresses,
     CIDR ranges, hashes and port numbers. Set at 17–18px, line-height 1.7, 68ch measure.

   Display: Bricolage Grotesque (600–800, optical-size axis)
     A grotesque with ink traps and a slightly quirky, warm character. Confident and
     youthful at 700–800 without the "hacker terminal" cliché; the opsz axis keeps large
     headings tight and smaller headings sturdy.

   Mono: JetBrains Mono (400–600)
     Tall x-height, slashed/dotted zero and clear l/1, built for reading code and logs;
     used for objective IDs, ports, firewall rules and log lines.
