  Palette (named):
    --ink        #12141c   base background, deep graphite-blue (not pure black)
    --panel      #1a1d29   card / panel surface
    --panel-2    #20242f   nested surface (table rows, inputs)
    --line       #2a2f3f   hairline borders
    --text       #d9dce6   primary text
    --dim        #7c8296   secondary / caption text
    --amber      #e8a33d   primary accent (terminal-phosphor signal)
    --amber-dim  #8a6a34   amber at low emphasis (borders, idle glyphs)
    --teal       #5fb3b3   info severity
    --red        #e0525f   high severity
    --green      #6fbf73   good / pass state
  Type:
    display/utility/data face: 'JetBrains Mono' — this is a byte-level
    inspection tool, so monospace is the *correct* register for the data,
    not a stylistic default.
    UI chrome face: 'Inter' — for nav, buttons, prose, so dense hex/mono
    text doesn't fight for attention with interface labels.
