/*
 * Axis Workflow - brand stylesheet
 * Part of the Axis Workflow Branding package. Do not edit in the development project:
 * changes are made in the SimAxis project and re-exported (see GUIDELINES.md, section 12).
 *
 * Location: works unchanged from Branding/css/ or _Axis/Branding/css/ - every path is relative.
 *
 * Load order: this file only. It declares the fonts (../fonts/), the design tokens,
 * base typography, and the brand components. Class names are prefixed "axis-" so they
 * never collide with host styles; the base layer is opt-in via the .axis-root class.
