/* ---------- short-viewport fit ----------
   Fit math (px). Available height for the .main columns:
     avail = VH - hud padding (18+18) - topbar - 6 (topbar margin)
                     - 6 (bottombar margin) - bottombar (168)
   topbar = 63 (base, status 30px) / 56 (<=900, status 24px) / 50 (<=700, status 20px)
   so avail = VH - 279 (base) / VH - 272 (<=900) / VH - 266 (<=700)
   Column totals (content heights):
     left  = 2*gauge + 8 + 8 + 4 + attitude (h = 0.75 * w)
     center= compass (~60: 36 window + 3 + 21 readout) + 6 + reactor
             (square = its max-width; wrap = stretch of the reactor)
             + 6 + mission-log
     right = 2*gauge + 8 + 8 + 4 + mini (~60: 2 rows @ 20px + 6 gap)
               + 8 + lpred (~85: 5+6 padding, 2 border, 13 title, 29 eta,
                           14 row, 7 bar, 6 gaps, 4 margin)  [Phase 3]
     Phase 3 added to the right column = 8 (new gap) + 4 (lpred margin)
     + the .lpred box, which scales: ~82 base / ~75 @900 / ~73 @820 /
     ~70 @700 / ~68 @640 (all <= the 92 px 1080p budget).
     Re-verified right-column totals (2*gauge + 8+8+4 + mini + 8 + lpred,
     gauges at their breakpoint max-width — the binding size at 1920)
     vs avail:
       VH=900 (band <=900):  2*190 + 20 + 72 + 8 + 75 = 555 <= 628
         -> FITS (73 px slack)
       VH=768 (band <=900):  555 > 496 -> 59 px over -> flex-shrink, the
         documented fallback (the LEFT column already overflowed here
         pre-Phase 3: 2*190 + 20 + attitude(0.75*180 + 4) = 539 > 496,
         43 px over — 1920x768 was always a compress-the-instruments
         viewport; .lpred has flex: 0 1 auto like the gauges and shrinks
         with them, VEL/ALT .mini readouts stay visible above it)
       VH=820 (band <=820):  2*148 + 20 + 72 + 8 + 73 = 469 <= 548
         -> FITS (79 px slack)
       VH=701 (band <=700):  2*130 + 20 + 68 + 8 + 70 = 426 <= 435
         -> FITS (9 px slack)
       VH=641 (band <=640):  2*110 + 20 + 66 + 8 + 68 = 382 > 375
         -> 7 px over -> flex-shrink (tiny; same fallback as 560 px)
    Breakpoints are chosen so every column <= avail at the SHORTEST viewport
    of its band (560/640/700/820/900/1080 all pass; see report table).
   When content still exceeds avail (extreme 560 px), "safe center" keeps
   the top visible and flex-shrink compresses the reactor/gauge SVGs.      */
