Texture

Block shades drawn as CSS lattices so they tile, print, and never wait on a face. Each step is a superset of the one before it, so a region can ramp without the pattern jumping. Ink defaults to the hairline. Never behind prose, never behind a table.

Scanline and column are the printout/CRT band. Hatch is the 45° screen-door on a locked fill. Dots are the specimen canvas — an 18px lattice quiet enough that a control's own edge stays the edge. The line grid is the same pitch as graph paper.

A texture may fill a vacant region, the inert half of a meter, or a disabled control. One textured region per view. Two reads as decoration. Set --tex-ink only when the lattice itself must carry the accent — almost never.

--tex-ink is local. The mark grade, not --accent: a lattice is a fill, and 3:1 is enough. Leave ink on the hairline unless the region is claiming the accent as its only job.

Three 1px lattices at coprime intervals. Roughly 0.4% coverage. A hero, a vacant canvas, the back of a print cover — never behind text, and never on the same screen as another texture.

Tractor-feed perforation down both sides. Only where the printout metaphor is the point — a receipt, a log export, a printed manifest. It is a frame, not a decoration.
