# Rüzgar Bisiklet — credits

Every asset this site ships, with source and licence. No photographs, HDRIs, models or AI imagery are used: the
bike (an engineering drawing built from `js/geo.js` by `js/bikesvg.js`), the compass card, the range rose, the
route profile and all other drawings are generated in code (SVG and Canvas 2D written for this site).
