Holographic card

Read first

Card.md for the card's name, subtitle, number, what the art shows, the foil and the frame; any art or style reference wired in. Keep a wired character or creature exactly as it is.

Card art (3:4)

• One subject, the card's hero, whole and centred in the upper two thirds, in a setting from Card.md, as a finished painted or rendered illustration.
• Clear depth: a foreground (the subject, maybe a near rock or leaf), a middle ground and a soft background, so the card can push them apart.
• Rich light with one bright source behind or beside the subject, and saturated colour that foil will make sing.
• No text, numbers, border, frame or card layout: the card adds those.

Depth map (3:4, from the art)

A grayscale depth map of the wired art, pixel-aligned: nearest white, farthest black, smooth gradients, the subject clearly in front, sharp edges where it overlaps the background, nothing of the art's colour or light.

Three.js card

• One complete page that fills the window on a dark backdrop with a soft glow behind the card, the card about three quarters of the window's height. The card is 63 × 88 mm in proportion with rounded corners, a thin edge and a back.
• Depth: the art on a finely divided plane displaced by the wired depth map, only toward the viewer (displacement bias 0: the farthest parts sit flat in the window, the subject comes forward), so the scene moves in parallax as the card tilts. Nothing of the card body, frame or back may ever show through the art: keep the art plane in front of them and the foil layer in front of the art's highest point. Tell the attached images apart by their descriptions (card art, depth map) and load each at its address exactly as listed.
• Foil: a rainbow holographic sheen (thin-film colours shifting with the view angle, faint fine diagonal lines) strongest on the frame, soft over the art's background and almost none over the subject, so the painting stays clear; gold or chrome when Card.md asks. It shifts as the card moves. Sparkle is sparse: a few percent of tiny round glints with soft falloff that flare as the angle passes them, never a grid of square pixels or a noise that reads as static.
• Frame: an embossed metal frame drawn into a canvas texture (with a bump map so the edges catch the light) with the name in a bold display face top left, the subtitle under it, the number and a short flavour line at the bottom, all from Card.md, spelt exactly. Small text sits on a solid plate in the frame's colour so it reads at every tilt.
• Back: a simple symmetric pattern in the frame's colours.
• Feel: the card leans toward the pointer, drag spins it with momentum, double-click flips it, it floats gently when left alone and turns back to its face. MeshPhysicalMaterial with clearcoat for the face, ACES filmic tone mapping, a key light and a rim light, OrbitControls off (the card moves, not the camera).

Avoid

Text or borders in the art, a flat picture with no depth, the card showing through gaps in the art, glitter that looks like static, foil so strong the art can't be seen, misspelt names, and a card that sits still.
