/*
 * هم‌نشست — landing page
 *
 * Tokens mirror the app theme (mobile/lib/core/theme): iris for the brand,
 * apricot for hands and highlights, mint for the speaking signal, warm paper
 * neutrals by day and "night" neutrals in the dark. Spacing sits on the app's
 * 4-point grid and radii match Radii.sm…xl, so the page and the app read as
 * one product. RTL throughout: logical properties only, no letter-spacing.
