/*
 * Dílna u Jasanu — stylesheet.
 *
 * Values are the mockup's own ("Dilna u Jasanu.dc.html", accepted 22.09):
 * container 1440/120, the five colours, Piazzolla 500–600 for headings,
 * Commissioner 400–600 for everything else, 1 px rules at 18–22 % brown,
 * corners 0–2 px, no shadows. Ochre sits only on rules, step numbers and
 * the active chip's border (handoff §4.2); "Detail →" is brown.
 *
 * Breakpoints: 1180 (gutters narrow), 860 (single column, the 390 mockup's
 * header and section layout), 480 (grids collapse).
