Changelog

[v0.2.1] — 2026-05-17

Money.Input.Components.money_input/1 no longer raises when the form submits an empty or unknown currency (e.g. the picker's hidden carrier before any selection). normalize_currency_code/1 blacklists "" and :"", and assign_money_locale_data/1 falls back to the locale's natural currency on unknown ISO codes instead of MatchError.
Money.Input.Components.currency_picker/1 tolerates an unknown locale — assign_picker/1 now falls back to a placeholder rather than crashing on {:ok, _} = ....
Dark-mode CSS tokens added — priv/static/money_input.css now ships @media (prefers-color-scheme: dark) and [data-theme="dark"] override blocks so the picker and money input pick up the host page's dark theme instead of staying light-themed.

Gettext-backed localization of the picker's UI strings (aria labels, search placeholder, section headers, empty-state). Catalog ships English source plus de, fr, and ja translations. Activated via Money.Input.Gettext backend. :gettext is now a required dep when the components are used (it was optional in 0.1).
Currency names in the picker rendering localize to the active locale via Localize.Currency.display_name/2 instead of the static English :name field.
Money.Input.Visualizer and the standalone helper have moved to the sibling money_input_playground package (under the MoneyInputPlayground.Visualizer namespace). Drops the :plug and :bandit optional deps from this package. If you embedded the visualizer in your own router via forward "/money-input", Money.Input.Visualizer, add {:money_input_playground, "~> 0.1", only: :dev} and update the forward target to MoneyInputPlayground.Visualizer.

Money.Input.Components.money_input/1 and Money.Input.Components.currency_picker/1 — locale-aware money HEEx components backed by an AutoNumeric JS hook, submitting %{"amount", "currency"} maps compatible with Money.Ecto.Composite.Type.
Money.Input.Cast, Money.Input.Validator, Money.Input.Currency, and Money.Input.Changeset — headless cast/validate layer with currency-aware precision (USD: 2, JPY: 0, BHD: 3) and an Ecto changeset bridge.
Money.Input.Visualizer — Plug-based development tool with light/dark theme toggle that demonstrates the components across CLDR locales and currencies.
