 * Locked-page approach on mobile (≤768px):
 * html/body are position:fixed; overflow:hidden — prevents iOS Safari from
 * scrolling the entire viewport when .chat-messages scrolls internally.
 * Only .chat-messages scrolls. All other elements (header, input, typing
 * indicator, reply bar) are flex-shrink:0 children of the .chat-main flex
 * column. This eliminates the position:fixed detachment bug on iOS.
 * Desktop (>768px) is unaffected — natural page scroll still works. */
