   PHASE 2.5 — Split-column glass redesign with slide-out modal.

   Layout (desktop ≥ 900px):
     • Left column   — 40vw, white glass surface, login form + logo.
     • Right column  — 60vw, ocean bg image + dark overlay + clock +
                        floating bubbles + announcement banner.
     • Slide-out     — anchored to form-column's right edge, slides
                        rightward to ~55vw width, covering most of
                        the showcase. Used for recover & register.

   Layout (mobile < 900px):
     • Single column, centered card, no bg images, no bubbles, no
       slide-out. Card-swap fade between login/register/recover.
     • Clock removed entirely (OS status bar already shows it).

   Class-name contracts preserved from earlier phases:
     .btn-login .spinner .btn-text .ft-alert .toggle-password
     .ft-input .input-group-icon .form-label .login-card
     .login-options .ft-check .forgot-link
