/* Spam Email Detection System — interface styles.
 *
 * A thin design layer over Bootstrap 5 (Table 3.3 of the report specifies
 * HTML5, CSS3 and Bootstrap 5, and that has not changed). Bootstrap supplies
 * the grid, the form controls and the JavaScript components; everything below
 * sets the type, colour and spacing on top of it.
 *
 * Two colour families are kept deliberately separate:
 *
 *   - the BRAND family, used for navigation, buttons and the sign-in panels;
 *   - the MODEL family — Random Forest, SVM and BERT — which matches the
 *     figures in Chapter Four so that the application and the written report
 *     read as one piece of work. These three values must not be changed.
 *
 * The verdict colours are not decoration either. FR14 requires spam and
 * legitimate mail to be visually distinguishable and model disagreement to be
 * highlighted, so green, red and amber each carry meaning.
