/*
 * Uitleg-voorbeeld: building blocks for the answer pages (factuur sturen als
 * particulier, factuur zonder KVK, belastingvrij bijverdienen). Visitors on
 * these pages are mostly not entrepreneurs and come for an answer, so the
 * blocks show the answer instead of describing it:
 *
 *   .uv-hero     answer on the left, the real thing (a nota, a sum) on the right
 *   .uv-col      one left-aligned reading column (verhaal-prose) with subheads
 *   .uv-paper    a readable example invoice/receipt with numbered pins that
 *                match .uv-notes; optional factuur/kwitantie switch
 *   .uv-wide     a figure that breaks out of the column (the spheres table)
 *   .uv-spheres  hobby / overig werk / onderneming side by side, one example each
 *   .uv-calc     a small worked example: opbrengst minus kosten, live inputs
 *
 * Built only from the landing tokens so light and dark both follow. Every
 * block is complete without JS; the script only adds the switch and the
 * live arithmetic.
