/* Phone frame for the hero capture; the 30-sec recording drops in here (Task 6).
   🚨 The frame must NOT impose its own aspect-ratio. It used to be 300/610, which after the
   12px bezel left an inner box of 276x586 = 0.471 — NARROWER than the screenshot's own
   1080/2000 = 0.540. `object-fit: cover` then scaled to height and threw away ~20px off EACH
   SIDE, which is why the German hero read "OKUMENT", "ECHNUNG AN", "OSITIONEN" and cut
   "Kunde ändern" (founder report, 2026-08-07, both languages).
   The rule, for whoever swaps the capture next: any box ratio ABOVE 0.540 crops the BOTTOM
   (harmless — the screen is meant to run off the frame); anything BELOW it eats the UI's left
   and right edges. Here the frame simply hugs the image, so nothing is cropped at all. */

/* ---- How-to (visual app tour — real app captures) ----
   🚨 SIZE IS THE WHOLE PROBLEM HERE, not resolution. These are real 1080x2000 captures of a
   412dp screen (~2.6 device px per dp), so the app's own ~15dp UI text is ~39 source px. The
   card width alone decides whether a reader can read it:
     4 columns in the 1080px container -> (1080 - 96 pad - 66 gaps) / 4 = 229px -> ~8 CSS px. Unreadable.
     2 columns                         -> (1080 - 96 - 22) / 2       = 481px -> ~17 CSS px. Comfortable.
     1 column on a 375px phone         ->                              335px -> ~12 CSS px. Fine.
   That is exactly the founder's report (2026-08-07, both languages): "at 100% zoom text is
   unreadable, but if zoom it - it looks good" — the assets were always fine, the display size
   was not. Cropping does NOT help: text spans the full width, so only width buys legibility.
   Hence two columns maximum. */

     shows the top ~81% of the screen — checked against the captures, which put every meaningful
