+  The launcher mark, and it is the same mark ServerScreen and LockedScreen draw: a square
+  outline in the accent with >_ inside it. Redrawn as a vector rather than exported as a
+  bitmap so there is one geometry to change and no set of five PNG densities to forget one
+  of.
+
+  #3CE88F is AccentColor from DodoSSH.Client.Shell's Theme/Palette.axaml, written out
+  because an Android resource cannot reference a XAML dictionary. The same duplication
+  colors.xml already carries for the window background, and the same rule applies: if the
+  palette moves, this moves with it.
+
+  108x108 with the artwork inside the middle 72 is the adaptive-icon contract — the outer
+  18 on each edge is what the launcher eats for masking and parallax. That 72 is a width,
+  though, and the mark is a square: its corners are what a circular mask reaches first. At
+  48 across the corners land 33.9 out against a radius of 36 and read as clipped even
+  though they technically clear it. 42 puts them at 29.7, which is margin one can see.
+
+  The stroke widths are the one place this deliberately departs from the screen. In the app
+  the box is a 1px border on 44px; scaled honestly that would be 1.0 here, and a launcher
+  drawing this at 48dp would render it at half a pixel and show nothing. 2.2 and 2.8 are
+  what keep it reading as the same hairline mark at the size it is actually looked at.
