# Yankı Festivali — credits and licences

A demo site by Olympos Web for a fictional festival. Every visual is drawn in code (WebGL, canvas, SVG, CSS);
every sound is synthesised in the browser with the Web Audio API (oscillators and a noise buffer). No
photographs, no recorded or AI-generated audio, no AI-generated imagery.

## Content

- Programme, artists ("Sanatçı 01–46"), stages, walking times, shuttle times and the site map are **example
  data** made for this demo. Prices, dates, venue, capacities, policies and contact details are **placeholders**.
- General advice (what to pack, hearing protection) is common safety guidance, not a claim about a festival.
- The melody approximates the Hicaz tetrachord in twelve-tone equal temperament; the page says so.
