/* Aviation Courses Limited — site stylesheet.
 *
 * The merge, in CSS terms: ACL-AI.Master gave the structure (Bootstrap grid, navbar,
 * footer columns) and ACL.css gave the identity. Every colour below is either taken
 * from ACL/ACL.css or derived from it, and each one says which.
 *
 * ACL.css is 479 lines of fixed pixel widths with no media query anywhere, so it is
 * not carried across verbatim — the values are, the layout is not.
