The prompt

Make a game about the Rosetta Stone in one HTML file.
Use cinematic, near-photorealistic 3D.
Start at a dig site near Rashid, Egypt, in 1799, at dusk. Add dust in the air, lantern light, and long shadows.
Let the player be a soldier in a 1799 French uniform, digging in the ruins of a fort.
Show an objective at top-left: "Uncover the three scripts." Show a timer at top center.
When the player finds each script, show a serif caption with one fact about it.
Then let the player decode Ptolemy's cartouche: match Greek letters to hieroglyph signs.
End on a ship at night on the Mediterranean, with the stone on deck under the moon.
Generate every image and every sound live from code.
Load no external files. Keep the file near 3 MB.
