Favicon

The symbol alone, in a square tile. The tile carries the silhouette, so the mark holds at 16px against light or dark browser chrome.

Clearspace

One module, 1x, taken from the lockup itself: the gap between mark and logotype is 0.5x, so 1x is twice it. Keep 1x clear on every side. Nothing sets inside it: no type, no rule, no edge of an image.

Grayscale

Twelve steps, near-neutral gray. 01 is the paper plate, 12 is the dark plate, structure pulls from between. Even lightness steps, one held hue. The archive ground sits below the ramp and is its own token.

Typography

EB Garamond says the things worth saying. Tekio is what you actually read. Numbers are always PX Grotesk. Weight stops at 500.

Atoms

Three forms in two states. Fill is matter, a hole is an opening in it. The six units make a constrained combinatorial grammar: they repeat, tile, mask, extrude, invert and animate without introducing any vocabulary from outside the set.

Consistency
Every larger composition is visibly built from the same source material.
Variation without drift
Graphics can change dramatically while staying recognizable.
Boolean logic
Fill and subtraction map directly onto vector operations.
Motion readiness
Holes can open and fills can propagate.
Multi-scale legibility
The same units work as icons, patterns, Shell faces and environmental graphics.
Machine-like construction
The system reads as procedural and generative rather than hand-decorated.

The Shell

Idler’s visual model of an environment: a closed, persistent structure in which agents move, act, and are evaluated.

One move

A layer turn. One or both outer layers of an axis, in either direction.

One pose

The Shell holds a single resting angle and never tilts.

Shapes persist

A shape only ever moves. A circle stays a circle through every turn.

Walk and return

It travels a set number of turns out, then comes back along the same path.

Faces retire by angle

A face fades as it turns away from you, before its marks could crowd.

One mark, one size

Every mark is drawn at the same size, everywhere, in every state.

The silhouette is the Shell

Nothing is stamped over the field. What you see is the object itself.
