Four surface materials, each carrying a distinct emotional register. The lock form is constant — the material tells you why.
Materials — the vocabulary of the lock
Brass
heritage · earned · warm
Achievement, trust, history. The heart-lock hero form.
Use: hero, shield state, milestones
Iridescent
queer · transparent · futurity
Chromatic glass — identity as spectrum. The pride lock.
Use: onboarding, community, hope
Frosted
private · translucent · calm
What's behind stays behind. Opacity as privacy.
Use: E2EE features, quiet states
Steel
utility · unsentimental · hard
The workbench. Infrastructure without drama.
Use: admin, audit tables, raw data
Motifs — the language carved into the material
PCB trace
Right-angle pathways with node dots. The lock's inner logic made visible — security you can inspect. Engrave into flat surfaces at 10–20% line weight vs. container edge.
Kintsugi seam
The spectrum scar where the shield was broken and repaired in gold. Used as section dividers and completion states. Never merely decorative.
Ember field
Warm amber particles on black — community memory, embers of the movement. Background ambience behind shields and hero moments. 20–40 particles max.
