/*
 * Design system of the operator's interface.
 *
 * Hand written because the project has no build step: what is served is what
 * is on disk. The vocabulary follows Material (elevation levels, a 4px grid,
 * outlined fields, state layers) so the result reads like the enterprise back
 * offices the operators already use, without pulling a component framework and
 * a bundler in behind it.
 *
 * Everything below is presentation. No business rule, no domain vocabulary
 * beyond the status tones, which `shared/status.js` maps.
