# Dep-light Dioxus UI kit (mirrors `@evinvest/uikit`). Renderer-agnostic RSX components;
# pulls only Dioxus + tailwind_fuse (the `cn!` engine). Unlike the kernel this
# library carries runtime deps — a UI kit can't be zero-dep; see AGENTS.md.
# `document`: the sonner toaster injects its stacking CSS through `document::Style`.

# PostHog product analytics (mirrors `@evinvest/analytics`). A small typed event
# API: native (Axum) async capture over `reqwest`; the Dioxus/wasm frontend POSTs
# the same payload via reqwest's fetch backend (no PostHog JS SDK). Carries runtime
# deps — opt-in, never in the kernel; see AGENTS.md.

# Error monitoring / Sentry (mirrors `@evinvest/error-monitoring`). Native (Axum)

# OpenTelemetry logs + traces over OTLP/gRPC (native backends only; the browser
# never links an OTLP stack). Two `tracing` layers + a flush guard, plus tonic
# interceptors for W3C trace propagation across the money-flow services.

# Frontend-only A/B testing (mirrors `@evinvest/experiments`). Cookie-bucketed
# weighted variant assignment for Dioxus; exposure is reported through an injected
# sink, so it never imports `analytics` (no cross-library coupling).
experiments = ["dep:dioxus", "dep:js-sys", "dep:web-sys", "dep:wasm-bindgen"]

# Five-locale i18n (mirrors `@evinvest/i18n`): locale registry, URL contract,
# Accept-Language negotiation, an ICU-subset formatter, the translation policy,
# and the `t!` macro. Wasm-safe and zero-dep *there* — the CLDR plural rules and
# number grouping for EV's five locales are hand-written rather than pulling in
# ICU4X, which would add megabytes of locale data to a Dioxus wasm bundle. The
# one dep, `inventory`, is native-only: it is how `t!` sites become a catalogue,
# and a shipped bundle extracts nothing.
i18n = ["dep:inventory"]

# Typed env settings (mirrors `@evinvest/settings`). The `settings!` macro reads
# env vars into a validated struct: aggregate error reporting, `= "literal"`
# defaults, `Option` = optional, `#[secret]` redaction. Env-only by design — no
# config files, no hot reload; sops/age decrypt at the shell/CI boundary and this
# library only reads the already-injected environment. Zero runtime deps.
settings = []

# Shared domain TypeObjects — PhoneNumber, Email, … — with validation.
# Zero runtime deps, wasm-safe (mirrors `@evinvest/types`).
types = []

# Producer SDK for landing-host microfrontends (see `mfe.rs` + the `mfe!` macro).
# wasm-only: the module is gated to `target_arch = "wasm32"`, so this is inert on
# native. A producer crate enables it; landing never compiles ev_lib at all.
# `wasm` pulls `dioxus?/web` + `web-sys`; `document` is for the bundle's `<link>`;
# `launch` is the `LaunchBuilder` behind `launch_into`, which a producer crate
# would otherwise have to enable itself for this feature to compile.
# `i18n` is not optional here: a producer declares its catalogue in the `mfe!`
# invocation, so an element remote cannot ship without having resolved its
# locale — which is the failure this pairing exists to make impossible.

#
# `Location` is not ours: dioxus-web 0.7.9's `history.rs` calls `window.location()`
# unconditionally but only declares `web-sys/Location` under its `devtools` feature,
# and `dioxus` depends on it with `default-features = false` — so a plain
# `dioxus/web` build fails to compile upstream. `dx build`/`dx serve` hide it by
# enabling `dioxus/devtools`; a bare `cargo check --target wasm32-unknown-unknown`
# does not. web-sys features unify across the graph, so declaring it here supplies
# the binding. Drop this once dioxus-web declares its own.
