   PDFDroid — Design System
   Black / red / white professional theme. Red is the single brand accent
   (buttons, links, focus glow, logo) against a near-black chrome (sidebar,
   footer, headings) and white content areas — matching the reference brief.
   Tool-category icon colors stay varied for at-a-glance scannability, the
   same pattern used by reference PDF tool dashboards.
