Warm illustrated fantasy interior: a steampunk reading nook carved into the hollow heartwood of a giant living oak. Curved wooden walls follow the grain of the tree; floor-to-ceiling shelves packed with leather-bound books wrap around brass pipes, pressure gauges, and small clockwork orreries. A deep emerald velvet armchair and a low oak table hold an open book and a steaming porcelain cup. Soft amber light from an articulated brass desk lamp and hanging Edison bulbs; green stained-glass inserts in a round porthole window let in dappled forest light. Living vines and moss frame the shelves without covering the books. Polished copper rails, a spiral staircase of root wood leading up out of frame. Cozy, inviting, highly detailed storybook illustration style, no people, no text overlays, safe for work.
