/* ---- short desktop windows: two fit tiers ----

   Owner rule (2026-08-03): panels never scroll -- overflow stays hidden.
   So when the window is short, the content itself must shrink to fit.
   The budget panel is DOUBT (8 lines[] entries -> ~21 wrapped text lines
   at the 380px panel width): 572px tall at full desktop type, which plus
   the panel's 4rem viewport margin stops fitting below ~636px of window
   height. That's a realistic desktop case (a 1366x768 laptop with normal
   browser chrome commonly lands around 560-620px innerHeight), not an
   extreme-zoom one, so it can't be left to the max-height clip above.

   Same technique as the mobile block: smaller title, tighter gaps,
   smaller line type, tighter inner padding. Two tiers so a 700px-tall
   window only pays a whisker of shrink and only genuinely short windows
   take the second notch (measured DOUBT heights, 1024px-wide viewport):
     <=700px tier: 508px -> fits every window >=572px tall.
     <=620px tier: 441px -> fits every window >=505px tall, well clear
       of the 560px floor this was tuned against; below ~505px the
       max-height clamp above resumes as the graceful-degradation net.

   The (min-width: 641px) guard is load-bearing, not decoration: a
   landscape phone can be simultaneously <=640px wide and <=700px tall,
   and without the guard these declarations would stack on top of the
   mobile bottom-sheet block above, which is its own separately-tuned
   layout. */
