   AVERTIZ — design system
   Palette:  --ink (near-black steel-navy), --paper (cool paper),
             --steel (primary brand blue), --amber (signal accent,
             drawn from safety/hazard signage — the one legitimate
             "bright" in this world), --slate (secondary text/rule)
   Type:     Times New Roman throughout (display, body and mono roles) —
             a system font, so no external font loading is required; this
             also makes the site lighter and faster to load.
