I'm a product design student. I'm not familiar with the terminal or writing code. Please build this for me with HTML, CSS, JavaScript and native Web Audio. Make a simple, usable browser page, with no external libraries or internet services. Sound should start only after I click. Use comfortable initial levels. I need to play with the result, not read code. Build a soundscape using only synthesis in Web Audio, no samples. Short bursts of white noise can make crackles; filtered noise swells can suggest wind; noise moving across stereo can suggest something passing. Give me separate controls for wind, water-like texture, crackles and a passing sound. Modulate the synthesised sources with slow LFO and smooth random movement so they keep changing. Let me adjust intensity and movement speed. Include a calm and a more restless setting. Keep it atmospheric rather than a row of beeps.
