Interactive banana plant rendered as translucent jelly

Build "Banana Jelly" — a single self-contained HTML file (no external requests, no libraries, no build step at runtime) using native WebGPU + WGSL. It is one entry in an editorial "MATERIAL STUDIES" series: an interactive, physically simulated banana plant whose every part is rendered as translucent coloured jelly. Simulation in JS, rendering in WebGPU; the page must stay smooth (sim < 2 ms/frame). PAGE / LAYOUT (editorial, warm paper) - Background paper #ece9e3 fading to a slightly darker floor; ink #241f1d; accent #c99a06 (banana gold); hairline rules #d5d0c8. - Top-left: small caps eyebrow "MATERIAL STUDIES", huge italic serif H1 "Banana / Jelly." (Iowan Old Style / Palatino / Georgia stack), short rule, caption "A little sway. A little slip. A whole bunch." - Top-right pill: green dot + "WEBGPU · LIVE" (or "WebGPU · Unavailable"). - Right floating glass panel (rgba paper, 1px border): • "THE TREE": dark button "Shake the tree" with a thin gold progress bar under it; tally row "On the bunch 31 · Fallen 0 · Peeled 0" (tabular mono numbers). • "PALETTE": three swatch buttons with a glossy jelly ball each — Cavendish (yellow), Red Dacca (red-purple), Blue Java (powder blue). • Sliders: Firmness 50, Internal damping 40, Breeze 30 (value shown in small mono at right). • Buttons: Reset · Pause · Reset view. - Bottom-left: "HOW TO HOLD IT", italic line "Shake the bunch. Swing the heart. Throw one hard.", and a small grey line: "Drag a leaf or the stem to bend it · pull a banana off and fling it — a hard landing bursts the peel · drag the purple heart to swing it
