/*
 * ZDES.lab admin panel: the one and only stylesheet.
 *
 * Served from the same origin (GET /static/admin.css, web/static_files.py),
 * because the Content-Security-Policy is default-src 'self': no inline
 * styles, no style="" attributes, no external fonts or images, no @import.
 * All interface texts live in content/admin.yaml, never in this file
 * (a test keeps Cyrillic out of it).
 *
 * Colour language, on purpose the same on every page:
 *   red     - instance PROD, guard banner, errors and refusals
 *   amber   - instance TEST, warnings
 *   green   - success
 *   blue    - links, the current page, the primary action
 * Rules for the coloured parts are flat (plain hex colours, no variables),
 * so tests/test_web_ui_layout.py can read the colour of each rule.
