WebGL-слайды о рождении чёрной дыры: от гаснущей звезды до аккреционного диска

Build an interactive WebGL slide presentation that tells how a black hole is born, as a single web page. Use a near-black space background and elegant serif headlines with one italic accent phrase in warm amber, small caption text, and a bottom chapter navigation with a play-journey button. Chapters: a star inside a nebula, a balanced white-blue star, a swelling orange star as fuel runs out, a collapse with an expanding shockwave ring, a dark event horizon, and finally a glowing accretion disk bending light around the hole. Animate smooth transitions of the central 3D object between chapters, with a procedural star surface, subtle star field and a lensed accretion disk. Let viewers play automatically or jump between chapters. Done means a polished, readable, continuous story that runs smoothly in the browser.
