/* The new page (2026-09-26): the Brain Terminal in the middle, the blocks as windows around it, one look.
   Three layouts, chosen by the screen's SHAPE rather than a device list:
   - wide (desktop, tablet landscape): cards left and right of the terminal, everything in one screen, no scroll;
   - almost square (a foldable iPhone or Galaxy Fold opened, an iPad portrait): the terminal on top, the seven cards
     in a band below it;
   - tall (a phone, a foldable closed): the terminal fills the screen, the cards follow as a two-column grid.
   A dual-screen device that reports two viewport segments puts the terminal on one and the cards on the other. */
