/*
  Design intent: this is a credentials console, not a data-entry form.
  The palette deliberately steps away from Bootstrap's default blue —
  ink/graphite neutrals with a single amber "key" accent, reserved for
  primary actions and anything security-relevant (secrets, warnings).
  Client IDs and secrets are always monospace to read as literal values,
  not prose.
