   vorpal.net — landing page
   Self-contained. No CDN, no external fonts, no framework.
   Brand purple #602671 (the Vorpal Boy logo color), lifted into a ramp so it
   stays legible on a near-black surface.

   Design note: nothing on this page encodes meaning in hue alone. Every
   comparison, state and category is carried by a text label, position, border
   or shape; color is decoration only.
