Subject: [PATCH] Theme : dark global ToolTip style
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

WPF's default ToolTip is a white-on-black system look that clashes
with the dark theme — visible whenever the user hovers a button with
ToolTip="…", a health banner pill, the « ⋯ » menu hint, etc.

Global TargetType=ToolTip style :
  Background  : Brush.Bg.Card
  Foreground  : Brush.Text.Primary
  Border      : Brush.Border, 1 px, 6 px corner radius
  Padding     : 12 × 8 (more breathing room than default)
  MaxWidth    : 360 — so the longer health-banner tooltips wrap to a
                second/third line instead of running off the right edge
  HasDropShadow : true (the only WPF-native cue that says « this is a
                  tooltip floating above » since we removed the OS skin)
  Inner TextBlock style cascades TextWrapping=Wrap on string-content
  tooltips so multi-line messages format nicely.
