shots: Mac App Store screenshots (mac size, APP_DESKTOP to the macOS version), a landscape layout (Mac window or bare; Mac, Play Chromebook, Play tablets), safe margins in every template checked by shots check from the render's layout boxes, a contact sheet timeout that scales with images, sizes and load; pitfall 80

 ## Unreleased
 
+- **Mac App Store screenshots.** `apple.mac: true` adds the `mac` size (2880 x 1800; `shots check` takes exactly
+  Apple's four 16:10 sizes, no alpha) and `apple screenshots --platform macos` uploads it as `APP_DESKTOP` to the macOS
+  version. `validate` notes a macOS version without Mac screenshots. Art pull maps `APP_DESKTOP` to `mac/`.
+- **Landscape layout** in both templates: copy column plus the frame in a Mac window or bare (`shots.landscape`), for
+  Mac, Play Chromebook (`play.chromebook`; no API type, `play images` links the console) and, with
+  `shots.landscape.playTablets`, Play's 7" / 10" tablet slots.
+- **Safe margins:** text and logo keep 7 % of the width left / right and 5 % of the height at the top in every
+  template (feature graphics too); `shots check` fails boxes under 6 % / 4 %, measured from the render's layout data.
+- **Contact sheet:** the `sheet.png` wait scales with the images, sizes and machine load, with a heartbeat, instead of
+  a flat 30 s.
+- iPhone Duo skip message says plainly that the API has no Duo type and names the console page.
