/*
  Design Plan:
  - Subject: Minimal, accessible event registration desk with attendance checks and badge/ID file upload.
  - Category / Context: Official summit registration & credential verification.
  - Palette: Crisp slate ground, deep carbon ink, signal ultramarine accent, muted border tones.
  - Type: Humanist / geometric system stack with high legibility.
  - The Live Thing: Authenticated attendee credential workspace with live database check updates and direct file receipt uploads.
