/**
 * Airpart estimate — styles.
 *
 * Token values copied verbatim from okko_crm `web/src/styles.css` so the two
 * estimate pages are the same document in two projects: same surfaces, same
 * borders, same teal accent family, same type scale, same slim scrollbar.
 *
 * The teal `--est-*` family is deliberately NOT the product palette. An estimate
 * is a commercial document that sits next to the product, so it carries its own
 * accent — changing a button inside the ERP must not repaint this chart. The
 * Airpart ERP's own functional colour system (SOW §6.4) lives in `tech_task/01`.
