/* The landing page (S-LAND). Same style pack as the app, `router`, and only its tokens.
 *
 * Three rules this file keeps, each for a reason the app already paid for:
 *   - logical properties only (`inline`, `block`), so Arabic needs no `[dir="rtl"]` twin —
 *     every twin is a place the two directions drift (S-WEB-9's RTL pass);
 *   - every control clears 44px under a finger, and a smaller LOOK never means a smaller
 *     hit area;
 *   - the chat-list preview is Telegram's, not ours (`preview.css`): inside `.tg` the
 *     colours are the client's, and the avatars below are the one addition.
 * A marketing page reads at 16px, not the app's 14: the app is a tool somebody works in,
 * this is something they read once before deciding.
