   ROMPUS INFORMATION NETWORK — shared stylesheet
   Vintage nautical journal meets Art Deco. Tokens + common components.
   Pages link this file, then may override tokens in a local :root block:
       <style>:root { --accent: var(--rust); }</style>
   Two page classes:
       body.hub      — Web treatment: Segoe body, cards, no border frames
       body.reading  — Editorial treatment: Georgia body, minimal chrome
