Print spec.

Optimised for legibility under any condition: bright sunlight, copy-pasted into Slack as a screenshot, printed on A4 and stuck to a server cabinet. Monospace throughout so columns line up without effort. Status conveyed by typeset glyph (● online · ▲ degraded · ○ offline) so the screen survives being read in greyscale. One accent colour, used only when something is wrong. Every horizontal rule earns its weight; weight encodes hierarchy.

Reference: Edward Tufte, vintage aerospace datasheets, restic's own --json output, the wireframe register but at maximum craft.

Risk: the most polarising of the three. Some readers will love the typographic discipline; others will read it as cold. There is no middle.
