BankSheetHandle class
The grab handle drawn at the top of a branded modal sheet.
The bar is a purely decorative affordance, but it must still be announced: a painted rounded rectangle contributes nothing to the semantics tree, so without a labelled Semantics container a screen-reader user gets no cue that the surface is draggable at all.
Sizing comes from the spacing scale (BankTokens.space10 wide, BankTokens.space1 tall, BankTokens.space3 of breathing room above and below) so the handle stays on the 4 pt grid at every text scale.
