/*
    rhf_apexpedia - the page.

    Civilopedia-shaped and deliberately quiet: one dark neutral, light text, ONE accent (the
    server's cyan) for links and the selected row only. Teko for headings, Inter for reading.

    NUI rules from the old server, all of which bit once:
      - no backdrop-filter (renders as a black rectangle), no color-mix() (some CEF builds drop
        the whole declaration);
      - [hidden] must win over every author display rule;
      - box-sizing reset from day one.
