   Component: mobile-apps — "Ứng dụng di động" (Homepage, 2026-10-09)

   Six DATPRO phone apps on one stage: pick an app on the left, its screens
   fan out as three floating phones that keep rotating (assets/js/mobile-apps.js).
   Every screen is an approved image in content/product-visuals.js, group
   "apps-v1" — real S22 captures (DAT CAR, DATCARE+, DATLIFE, DATEDU KIDS) or
   the client's design mockups (DATWORK, DAT HOME). Each panel says which of
   the two it is, so a design never reads as a shipped screen.

   Light theme on purpose (client: no dark navy, "lấy màu gốc"): the stage is
   tinted with the active app's own brand colours via --c / --c2, which the
   markup sets per app. Every selector is .ma- prefixed.
