/* ============================================================================
   BucketBill — Solutions + documentation pages (static, crawlable)
   Shared by every generated page under /docs/ and /solutions.html.
   Palette mirrors the live app's navy/blue tokens (projects/landing/styles.scss)
   so the docs read as part of the same site — NOT the olive/lime legal pages.
   Self-contained: these static files do not load the Angular CSS bundle.
   No inline styles anywhere in the HTML, so the pages' CSP stays style-src 'self'.
   Accessibility: --bb-sky is decorative only (fails WCAG on white); body text
   and links use --bb-text / --bb-accent, which pass on white.
