/*
 * 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    - the current page, the primary action, neutral news
 *   teal    - links and the focus ring
 * The look follows cards.zdeslab.ru (ADMIN-RESKIN.md); the site orange is
 * not used anywhere: it is too close to the amber TEST plate.
 * 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.
 * The whole palette is listed here; tests/test_admin_reskin.py checks that
 * every colour of the file is one of these and that none is missing.
 *
 * Site:
 *   #06131c ink: text, hover of the primary button
 *   #063d59 blue: primary button, current menu item, info
 *   #0d8b96 teal: focus ring, preview stripe
 *   #0b6d78 dark teal: links (teal itself is too pale for text)
 *   #f3f0e9 cream: page background
 *   #ffffff white: header, fields, tables, plain buttons
 *   #dff5f2 mint: hover of buttons and menu
 *   #e7f0ed sage: table header
 *   #faf8f3 paper: zebra rows
 *   #d6d1c4 line: borders of tables, cards, header
 *   #45535a grey text: hints
 *   #5f676b grey border: fields
 * Signals:
 *   #c62828 #7f0000 #7f1d1d #fdecea red
 *   #ffb300 #b26a00 #1f1a00 #f9a825 #5f4300 #fff8e1 amber
 *   #2e7d32 #14421a #e8f5e9 green
 *   #e0ebf5 info background
 *   #06131c1f card shadow (the only eight-digit colour)
