Wagyu Wallet · Set two · “Human”

Design 13 — Postmark

Rationale

Letters, not notifications. The wallet as a well-run post desk: kraft envelopes, airmail chevrons, ink postmarks, the satisfying thump of a stamp. Privacy is the sealed envelope — the postal service carries it, nobody reads it, and the postmark proves it arrived. Friendly, physical, a little romantic about mail.

Risk

Postal nostalgia could read kitsch. Countered with functional colour (airmail red/blue as wayfinding, not decoration), a crisp grid, and modern typographic scale. The ephemera is the skin; the skeleton is a current-year finance app.

Muse

Airmail ephemera and mid-century postal design — the chevron border, the round date stamp.

Motion personality — “postal”

Letters slide into slots (lateral, 300ms, cubic-bezier(0.32,0.72,0,1)); stamps thump (scale 1.15→1, 160ms snap, slight rotation); flaps fold (rotateX). Press = paper press (translateY 1px). The confidence of a rubber stamp hitting paper.

S15 – S16 · empty wallet, errors

An empty tray invites the first letter; an error explains, reassures, and directs.

Nothing in the tray yet. Every post desk starts empty. The first letter is the good part.
