/*
  Design notes (kept here rather than left implicit):
  - Subject: internal back-office for a domain registration platform. Audience: admin staff
    processing registrations, pricing, suppliers - technical, detail-dense work.
  - Palette: graphite sidebar (#14161B) against a warm paper content area (#FBFAF7), a single
    indigo accent (#3454D1) for actions/links, amber (#C77B12) for warnings, muted red (#B3432B)
    for destructive/errors, green (#2F7D5C) for success/active states.
  - Type: Inter for UI text (clear at small sizes, dense tables), ui-monospace for anything
    that's technically an identifier - domain names, TLDs, IPs, action codes, invoice numbers -
    since that's the actual vocabulary of this tool and monospace makes those scannable in a table.
  - Signature: the sidebar header reads like a terminal prompt ("admin@registry:~$"), a quiet nod
    to the technical subject without being a gimmick applied elsewhere on the page.
