/* tt-login.css — TT-branded login page served at /talking-time.
 *
 * Scoped under .tt-login so none of these styles leak into the LINGO area
 * or the authenticated TT dashboard (.tt-area). All modal / button / input
 * styles are defined locally so this file is self-contained and does not
 * depend on index.html's global .btn / .form-group rules.
 *
 * Feature: talking-time-module spec, Task 5.7.
 * Requirements 3.6, 3.7, 3.8, 5.1, 5.2, 5.3.
