Rename the old blue/green default scheme to "DXPR Theme 2025" and replace it with a monochrome palette. Update install defaults for layout, typography, header, and menu settings. Add post-update hook to migrate existing sites to the renamed scheme.
Update $primary, $accent1, $accent2, and all color fallback variables in _variables.scss to match the new default monochrome scheme. Rebuild bootstrap-theme.css which uses $primary and $gray-light directly.
The shipped CSS custom property defaults in variables.scss must match the install config, otherwise fresh installs render old values until the Theme Settings form is opened. Updated: headings-line-height (1.1 -> 1.2), scale-factor (1.34 -> 1.25), menu-link-spacing (10px -> 20px), headings-bold (normal -> bold).
