/* Invaris Brokerage — foundation layer.
 *
 * ORIGIN: adapted from coherence/apps/coherence-ui/public/styles.css.
 * Token values, shell grid, rail geometry, and component metrics are carried
 * over verbatim so the brokerage inherits Coherence's actual visual language
 * rather than an approximation of it. Coherence itself is never modified.
 *
 * What was deliberately NOT copied: the chat product's surfaces (message
 * stream, composer, repair review, settings panels). That is ~100 KB of
 * selectors for workflows this app does not have. Copying them wholesale is
 * the "over-copying" failure the adaptation plan warns about.
 *
 * Naming: Coherence's class names are retained where the element plays the
 * same structural role (.top-rail, .workspace, .list-item), because matching
 * names is what lets a change in either app be read across both.
 */
