Orbit ring and wallet

Programmatic background of animated dots — each dot lives in its own Voronoi cell and orbits around the cell center, rotating individually. 3×3 cell scan finds the closest dot, and a 1–10 color palette is sampled with optional step quantization. Randomizers use hash functions so no noise texture is bound.

Requires iOS 18+ / macOS 15+ (SwiftUI ShaderLibrary / Shader / Metal stitchable).

SWWallet is a playful wallet "pocket" that holds a stack of payment cards. Three (or more) cards are tucked into an olive-green pouch from the top opening: the upper half of each card peeks out while the lower half slides behind the wallet's front panel, creating a real "card inserted into a pocket" look. The front panel shows the combined total balance plus a "Total Balance" caption and an eye toggle that reveals or hides every amount at once.

Two states, driven by a single isRevealed flag:

1. Hidden (default) — cards are tucked deep into the pouch and stacked on top of each other; the total reads as a row of bullets (••••••) and the eye button shows eye.slash.
2. Revealed — cards spring out one after another into a staggered ladder (first card highest, last card nearest the pocket opening); the total morphs into the real sum (thousands-separated) and the eye button shows eye.

The staggered "pop out" is built from a per-card .animation modifier with a .delay(index * 0.07), so each card bounces out slightly after the previous one. Number changes use .contentTransition(.numericText()) so the bullets and digits cross-fade smoothly.

Layering (ZStack, bottom to top):

1. Card layer — a RoundedRectangle per card carrying a bold text wordmark and its balance. The lower half is intentionally covered by the front panel. zIndex keeps the ladder stacked correctly.
2. Wallet front panel (the pocket) — an UnevenRoundedRectangle filled with walletColor, overlapping the lower half of the cards. Its top edge is the pocket opening. The panel carries: white dashed stitching inset along its edge, the big rounded total balance + caption, and the eye toggle button at the bottom center.

Brand note: wordmarks are rendered as plain bold Text only — no official brand logo image assets are bundled (this is a public repo). Swap the SWWalletCard.sample data for your own accounts.

On `currencyCode`: amounts are formatted with .currency(code:), so the symbol and grouping follow the supplied ISO currency code and the device locale.
