feat(ui): add USDF "$" watermark to the Dollars token card - #1250
Merged
Conversation
Draw an oversized bold "$" glyph bleeding off the top-right of the gold USDF/Dollars card, using mix-blend "overlay" at 30% so it reads as an emboss on the gradient rather than a solid mark (Figma 9120:15335). Gated to USDF (token.address == Mint.usdf); other tokens are unchanged. The glyph is pre-measured with a TextMeasurer and its font size is expressed in dp (via toSp) so it scales with the card height and ignores the user font scale. It's drawn in a drawWithContent layer that sits above the gradient, is clipped to the card's rounded shape, and ignores the content padding. Adds a render-only Robolectric harness (TokenCardWatermarkScreenshotTest) that captures the card to build/screenshots/ for eyeballing the mark without an emulator.
Replace the hardcoded 16.dp top-bleed / right-inset constants with CodeTheme.dimens.inset so the watermark tracks the card's content inset and flips to 16dp automatically on the 4pt-grid switch.

Adds
TokenCardWatermarkScreenshotTest— a render-only Robolectric harness (native graphics) that captures the card tobuild/screenshots/so the mark can be eyeballed without an emulator. It's not an assertion test.Verified visually: the gold Dollars card shows the
$; a non-USDF (USDC) card renders with no watermark.
