/* ============================================================
   1a corrections — measured against the design, not the description.

   Two things the first pass got wrong:

   1. THE COLUMNS STILL STOPPED HALFWAY. 1a's whole board is a grid
      (grid-template-columns:repeat(4,1fr)); the flex track kept the old fixed 288px
      basis, so on a 1536px dialog three status columns filled 900px and the right
      two-fifths stayed empty — the exact defect 1a was drawn to fix. auto-fit rather
      than a literal 4: this board also groups by Priority (5) and Due Date (6), so a
      hard column count would either overflow or strand cells.

   2. THE ACCENT RESOLVED TO NAVY. 1a's active tab underline is #155DFC and its selected
      Group-by segment is #D8E2F8; both were wired to --mud-palette-primary, which in this
      theme is near-black (#0B1220), so the selected states came back grey. The accent is
      a local literal here, the same way every other Design D surface file carries its own
      (--adx-brand, --gsh-accent, --alc-brand).

   A FIXED SHELL. The dialog used to size itself to the board: three columns and it was
   short, a full Open column and it was tall, and switching Board/Calendar or Group by
   resized it under the pointer — the Add To Do button and the tab strip moved every time
   the content changed. Everything inside was doing its own viewport arithmetic
   (max-height: calc(100dvh - 380px) on the board, calc(100dvh - 360px) on the calendar,
   calc(100dvh - 280px) per column), so three different sums decided the height and none
   of them agreed.

   Now one rule owns it: the dialog is a fixed-height flex column, the title bar and
   toolbar are auto-height, and the ground is the single scroll box. min-height:0 on every
   flex child is load-bearing — a flex item's default min-height:auto refuses to shrink
   below its content, which is exactly how a "fixed" height silently grows again.

   Fullscreen (UIConstants.IsCompactView passes FullScreen) is excluded: MudBlazor sizes
   that itself, and a calc() height there would leave a gap at the bottom of the screen.
