An icon set where every mark has a number and a stated meaning, rather than a bag of glyphs. The precedent is Ron Cobb's Semiotic Standard, and the precedent is all that transfers — 🔴 the artwork, the names and the trademarks are not ours to relicense, and the idea was the valuable half anyway. These are authored here, in tools/icons.py, which is the register and the source.

⭐ The frame is the category and the mark is the meaning. That is decoration needs a rule applied to iconography, and it gives the set a property almost no icon font has: an unfamiliar symbol is still half-readable, because the triangle tells you it is a hazard before you have worked out what is inside it. The number carries the same information, so a symbol referred to by number alone is also half-understood — and because both say it, they can be checked against each other. They are: tools/gen_icons.py refuses to emit if any symbol has drifted out of its family.

The set is eight families of at most nine marks, which is what two digits can number. The first five report on a machine — what it is doing, what will hurt you, which part you are looking at, what is moving through it, what you may do to it. The last three are about the ship and the people in it, which is the half of the precedent a console-only set leaves out and the half that is actually painted on bulkheads. 🔴 The ninth tens digit is deliberately unspent: a register that fills its own numbering the moment it can has no room to be wrong about a category later.

⭐ A mark never crowds its frame, because the frame is what carries the category and it has to survive being looked at quickly. tools/clearance.py measures the visible gap on every symbol and refuses if any is tight — and the margin is not one number, because the frames are not the same size inside. The margin is one ninth of the room the frame has: the state circle holds an inscribed disc of 9.00 and the hazard triangle holds 5.40, so one figure generous enough for the circle would shrink hazard marks back to the size that already failed a pass. Every frame gives up the same proportion of its interior instead.

Asking what one means

The refusal, which is the whole difference

Ten themes

Every stroke is currentColor, so a symbol takes the surrounding ink and therefore the theme, with no per-theme rule anywhere and no second implementation.
