/*
 * Labby App Stylesheet
 * -----------------------------------------------------------------------------
 * Contributor map:
 *  1. Base variables and shared components define the visual language.
 *  2. Desktop layout rules come first and must remain compatible with wide screens.
 *  3. Mobile behavior lives under @media (max-width: 1100px).
 *  4. Dialogs, sheets and rack-specific rules are grouped by feature.
 *
 * Style guide:
 *  - Reuse CSS variables instead of hard-coded theme colors.
 *  - Keep tap targets at least 44px on mobile.
 *  - Add new mobile-only fixes inside the mobile media block whenever possible.
