                           Wait, if they are siblings, they are NOT inside the track.
                           The user request says "Mettre les icônes dans le track en position: absolute".
                           BUT the HTML structure in previous steps (and user prompt) showed:
                           <button ...>
                             <span class="icon sun"></span>
                             <span class="track"></span>
                             <span class="thumb"></span>
                             <span class="icon moon"></span>
                           </button>
                           So icons are OUTSIDE the track.
                           However, the prompt asks to ensure thumb doesn't cover icons OR icons are above.
                           If icons are outside (left/right of track), thumb (inside track) can never cover them.
                           Let's check if the user wants icons INSIDE the track.
                           "En mode clair, le thumb n’est pas centré et passe sur l’icône soleil."
                           This implies icons MIGHT be inside or visual overlap is happening.
                           Let's stick to the prompt's suggestion: "Mettre les icônes dans le track en position: absolute...".
                           To do this without changing HTML, we can position them relative to the button (.theme-toggle).
                           
                           Let's position icons absolutely within .theme-toggle button, over the track.
                        */
    top: 50%;
    transform: translateY(-50%);

.theme-toggle__icon--sun {
    left: 6px; /* Inside the track, left side */

}

.theme-toggle__icon--moon {
    right: 6px; /* Inside the track, right side */
    color: #f1c40f;
    opacity: 0.5;
}

/* Adjust track width to accommodate icons if they were outside, but now we put them inside visually?
   Actually, the prompt says: "Mettre les icônes dans le track en position: absolute".
   But HTML is button > icon, track, thumb, icon.
   We can position icons absolute relative to BUTTON.
   And make the TRACK full width of the button?
   
   Better approach based on prompt "En mode clair, le thumb ... passe sur l’icône soleil":
   This means visual overlap.
   Let's make the track contain everything visually.
   
   Let's set .theme-toggle width to var(--toggle-width).
   And make icons sit inside.
