/* Theme contract: neutral defaults shared by every theme.
 *
 * Loaded BEFORE the active theme CSS in templates/base.html so missing
 * variables in a theme don't leave unstyled regions. Each themes/<slug>.css
 * is expected to override every var here in its own :root block;
 * tests/test_themes.py verifies the contract is satisfied.
 *
 * Adding a new variable: declare it here AND in every theme file. The
 * contract test will fail otherwise.
