P1 Stream B: port iOS brand assets to Android

- outline, tab_view, app_icon_mark, widget_icon: rasterized from iOS
  PDF/PNG sources at 1024px (gradients/shadows would flatten via SVG trace)
- honeycomb_texture: hand-authored VectorDrawable, seamless hex tiling
  verified at 4x4 render
- widget_icon: adaptive icon (mipmap-anydpi-v26) + density-specific
  mipmap + foreground bitmaps (mdpi..xxxhdpi)
- Source PDFs preserved in docs/ios-parity/source-assets/ for future
  re-rasterization

AssetInventoryTest asserts all 5 Res.drawable entries resolve.

+  honeycomb_texture
+
+  Seamlessly tileable honeycomb pattern, mimicking the faint hex grid in
+  iOS outline.pdf / tab_view. Meant to be painted as a repeating tile via
+  Compose (e.g. Brush.tile or Modifier.drawBehind { drawImage(tileMode=Repeated) }).
+
+  Geometry — pointy-top hexagons (flat sides left/right, points top/bottom),
+  side length s = 10.
+    W = sqrt(3) * s = 17.3205   (hexagon width)
+    Row vertical step (center-to-center) = 1.5 * s = 15
+    Two rows = 30u vertical period
+    Tile size = W x 30 = 17.3205 x 30
+
+  Row 0 has hex centers at x = 0, W, 2W, ...
+  Row 1 (offset) has hex centers at x = W/2, 3W/2, ...  (offset by +W/2)
+  Row 2 aligns with Row 0 again.
+
+  In one W x 30 tile we need:
+    - Row 0 center at (0, 0): partial, 4 corners at tile corners → contributes 1/4 hex each to 4 adjacent tiles.
+    - Row 0 center at (W, 0): same (tile corners on right edge).
+    - Row 1 center at (W/2, 15): fully inside tile.
+
+  Stroke: amber @ ~20% alpha via android:tint, so it reads as subtle background.
