Create an original, polished, genuinely eerie browser horror game called LAST LIGHT. The player is alone in an abandoned research station and must restore three emergency generators, then reach the exit, while something hunts them. Make it tense and visually striking enough to watch in a YouTube video. No gore, copyrighted characters, external libraries, network requests, or downloaded assets. Use only inline HTML, CSS, JavaScript, Canvas, and optional synthesized Web Audio. It must work offline as one index.html file at 1280x720 and adapt to other desktop sizes. Controls: WASD or arrow keys to move, E to interact, Shift to sprint, R to restart. Include an obvious clickable Start button, clear on-screen controls and objective, readable generator progress, a win state and a lose state. Aim for a complete 60-90 second round. You choose the visual style and mechanics. Make the first 15 seconds interesting. Avoid rapid flashing/strobing and extreme audio levels.

This is a one-response creation challenge. Do not use tools, read files, browse, ask questions, or run tests. Return only the complete HTML document, starting with <!DOCTYPE html> and ending with </html>, without markdown fences or explanatory prose. Keep the entire implementation below 22000 characters. This exact brief is being given separately to both contestants; you cannot see the other entry.
