70Materia. The UI is the mount, never the artwork.

70Materia is a neutral frame built to disappear around its content — a curated material library where the UI chrome is deliberately invisible so stone, terrazzo, and pigment samples can dominate. Every typographic element sits at weight 400 in a single sans family (Matter), with a monospace companion (Matter Mono) used for labels, navigation, and small UI controls. Letter-spacing on the mono (0.02em–0.04em) plus tabular numerals gives the interface a spec-sheet, architectural-drawing quality — as if the page itself is a technical sample board. The palette is strictly achromatic: black text, white surfaces, and a warm mid-gray canvas (#bababa) that recedes behind the photography. Buttons are thin, square, and outlined; the only filled surface is a near-black (#1e1e1e) for select actions and the footer. No accent color exists in the system — all chromatic energy is outsourced to the product photography.
