White background with parchment-tinted surfaces (#F5F4F0). That warm off-white has the slightest yellow-green undertone that reads as aged paper. Not cold. Not clinical. Comfortable. The kind of surface you associate with a well-used notebook.

Rubik for headings at weight 700. Geometric with subtly rounded terminals that give it personality without sacrificing authority. The slight negative letter-spacing (-0.01em) brings characters together just enough to feel intentional. Bold Rubik headlines anchor the warm palette with confidence.

Libre Baskerville for body text is the real statement. A serif body font in a developer tool. It reads like a well-typeset book. The 1.6 line-height (rendered at 1.7 in the full prompt) gives every line of content the breathing room that long-form reading demands. The pairing of a geometric sans heading with a literary serif body creates the exact tension of "engineer meets author."

Soft layered shadows that create convincing depth at two scales. A gentle 4px-16px primary shadow for cards, a tighter 2px-6px shadow for buttons and inputs. The large shadow at 25px-50px offset creates dramatic depth for modal and overlay moments. This is a three-tier depth system that knows exactly when to be subtle and when to make a statement. The lift hover effect reinforces the paper metaphor. Content rises like a page turning.
