📜 Intro

A highly customizable, accessible OTP (One-Time Password) input component for WASM frameworks: Yew, Dioxus, and Leptos.

Supports animated per-slot digit entry with automatic focus traversal, primary and secondary visual variants, built-in HOTP/TOTP validation per RFC 4226 and RFC 6238, and full WCAG compliance.

🤔 Why OTP RS?

1. 🎨 Fully Customizable: Control every attribute, class, style, variant, pattern, ARIA labels and more, on the outermost container, each group, each slot, and each separator.
2. ⌨ Smart Focus Management: Typing a digit automatically advances focus. Backspace regresses focus. Arrow keys navigate left and right.
3. ✨ Animated Entry: Each digit pops with a scale animation when entered, and a blinking caret is shown in the active empty slot.
4. 🔐 Built-in Validation: Validate against HOTP (RFC 4226) or TOTP (RFC 6238) using a pure-Rust implementation, no C, no external crypto crates.
5. ♿ Accessible by Default: role="group", aria-label, inputmode, autocomplete="one-time-code", disabled/invalid data-attributes all wired up automatically.
6. 🧩 Framework Agnostic: Same API semantics across Yew, Dioxus, and Leptos.
