 * The dresses the canvas can wear (ADR 0148).

 * Five looks for how subjects and edges draw, all over the same notation -
 * shapes by aspect, arrowheads by kind, glyphs, badges - so only the dress
 * changes and never what a shape means. Each preset is a list of stylesheet
 * blocks appended after the base and notation rules, so it wins on the
 * properties it names and inherits everything else; `current` appends
 * nothing. A style is the reviewer's, not the view's: it is remembered in the
 * browser and never written into a projection.
