Create a polished Tetris-style falling-block game. Use a standard 10x20 board, all 7 tetrominoes with distinct colors, rotation with simple wall kicks, soft drop (down arrow), hard drop (space), line clears with a short flash animation, score, level and a next-piece preview, increasing speed per level, and a game-over screen with restart on R. Controls: left/right arrows move, up arrow rotates. The game starts immediately.

Requirements for your answer: output ONE complete, self-contained HTML file in a single ```html code block. Inline all CSS and JavaScript. Do not use any external libraries, CDNs, web fonts, images or network requests; it must work offline by simply opening the file in Chrome. It must fill a 1920x1080 browser window nicely and start immediately on load without requiring a click.

Write a physics simulation of 20 numbered balls bouncing inside a spinning hexagon. The hexagon rotates continuously around its center. The balls are affected by gravity and friction, collide realistically with the rotating walls (take the wall's motion into account) and with each other. Every ball has its own color and shows its number. Implement collision detection and response yourself, no physics library.

Render an animated 3D scene using only the HTML canvas (raw WebGL, or Canvas 2D with your own projection math; no libraries): a small low-poly island with trees and a lighthouse whose light beam rotates, surrounded by animated water, while the camera slowly orbits the island. Include simple directional lighting and correct depth ordering.

Create a detailed SVG illustration of a cozy mountain cabin at night: snowy mountains, a pine forest, a cabin with warm glowing windows and smoke from the chimney, a starry sky with a moon and green northern lights. Use gradients and layering for depth. Add subtle animation (twinkling stars, drifting smoke, waving aurora) with SVG or CSS animation. The SVG must scale to fill the whole window.

Build a small personal finance tracker web app: add income and expense entries (description, amount, category, date) via a form, show a list that can be sorted and filtered, live totals and the balance, and a donut or bar chart of expenses per category drawn with canvas or SVG (no chart library). Persist the data in localStorage and pre-fill 12 realistic example entries on first load so the app looks populated. Modern, clean design.
