/* Pattern rendering. Every mock is laid out at its design size (mobile 390x845,
   web 1280x800) in plain px and scaled to its card with a transform; the scale
   factor --z is set by SpecimenPatterns.fit() from a ResizeObserver.
   Colors come from semantic role tokens only (--b-bg/surface/text/action/ring/selected/
   brand/highlight/status). Never reference a seed or a primitive step here. Discrete
   component variants come from data-b-* attributes on an ancestor (SpecimenBrand.apply). */
