A PRESENTATION ATTRIBUTE (`fill="var(--x)"`) // does not resolve — it is parsed as an SVG paint value, not a CSS property, // so the shape renders black. The sanitiser keeps `style`, which is what // makes this work at all. // - The belt tiers stay LITERAL. Yellow/red/blue are the game's own tiers, the // way a green circuit board is green; theming them would say something false. // Same rule the sprite palettes use: tokens for structure, literals for // things that ARE a colour. The ACTIVE pill's label is literal for the same // reason: what it has to contrast with is the belt colour, not the theme, so // `--accent-ink` there was dark blue on red on a light theme. factory floor = svg(``) // @label(The line, drawn) @wide @icon(px:assembler) machines in the line = round(_machines, 1) // @hero @label(Machines) @icon(px:assembler) @note(assemblers + furnaces, and the belt pills above are clickable) # Flow @tab @icon(px:belt) chain flow = sankey([["Iron ore", "Iron plate", _flow("Iron ore")], ["Copper ore", "Copper plate", _flow("Copper ore")], ["Iron plate", "Circuit", _flow("Iron plate")], ["Copper plate", "Cable", _flow("Copper plate")], ["Cable", "Circuit", _flow("Copper cable")]]) // @label(Items per second) @icon(px:belt) /// The cable branch is thicker than the circuit branch it feeds: 1 circuit wants 3 cable, 1 craft makes 2.

Stone and steel furnaces burn fuel rather than electricity, so their power reads zero and their coal is not costed. Inserter throughput, drill placement and mining productivity research are ignored. Belt rates are the standard 15 / 30 / 45 per second. > The chain is a fixed tree. Where an item has SEVERAL recipes — oil cracking, coal liquefaction, Kovarex — something has to choose between them, and that is a linear program, not the square solve `linsolve()` provides.
