Altitude operates in a midnight editorial register: near-black canvas, off-white serif headlines (Libre Baskerville), and razor-thin secondary type (Inter). The serif-on-dark pairing is the signature — most AI finance tools lean on geometric sans-serifs; Altitude borrows from financial print (WSJ, FT) to signal authority and discretion. Mountain ridge linework and painterly landscape photography replace the usual gradient meshes and 3D renders, grounding the AI product in a sense of summit and scale. Surfaces are stratified by barely-perceptible gray steps (#111 → #181 → #1f → #26 → #32), with hairline borders doing the structural work that shadows do elsewhere. Color is almost entirely absent from the interface — when it appears, it reads as functional punctuation rather than decoration. Components are tight, rectangular (4–8px radii), and content-forward.
