Dioxus CSS Asset fails to load during serve (Android)

---
**Problem**

A CSS file referenced with Dioxus asset! in an Android app does not load during dx serve --platform android.

The stylesheet exists at assets/tailwind.css and is referenced from the document head with:

document::Stylesheet { href: asset!("/assets/tailwind.css") }

Dioxus emits a hashed URL like:

/assets/tailwind-dxh935a5e23476ca8af.css

The Android build copies that hashed CSS into the generated Android asset bundle, but the dev HTTP server does not serve the same file from /assets/..., so the browser/WebView request returns 404 and the page renders without styling.

**Steps To Reproduce**

Steps to reproduce the behavior:

- Clone or open the minimal repro project in this directory: https://github.com/rdelacrz/dioxus-asset-404-repo
- From the repro root, run:

cargo check --no-default-features --features web
python3 verify_repro.py

- The script starts:

dx serve --platform android --port 8099 --watch false --hot-reload false --interactive false

- Observe that the hashed CSS exists in Android output:

target/dx/dioxus-android-asset-404-repro/debug/android/app/app/src/main/assets/tailwind-dxh*.css

- Observe that the matching file is missing from the dev server public assets directory:

target/dx/dioxus-android-asset-404-repro/debug/web/public/assets/

- Observe that the dev-server URL returns 404:

http://127.0.0.1:8099/assets/tailwind-dxh*.css

**Expected behavior**

A stylesheet referenced with asset!("/assets/tailwind.css") should load successfully during Android dx serve.

From the Dioxus side, Android asset! output and dev-server /assets/... serving should use the same asset source in dev mode. Possible fixes:

- copy/sync Android client hashed assets into the fullstack/dev server public assets directory;
- serve Android bundled assets through the /assets/... dev-server route;
- or generate Android dev URLs that route through the native Android asset resolver instead of the HTTP server.

. The automated repro prints the failing condition:

Android hashed asset exists: .../android/app/app/src/main/assets/tailwind-dxh935a5e23476ca8af.css
Matching server public asset exists: False
Requesting dev-server asset URL: http://127.0.0.1:8099/assets/tailwind-dxh935a5e23476ca8af.css
Observed HTTP status: 404
Confirmed repro: Android asset exists, but dev-server /assets URL returns 404.

**Environment:**

- Dioxus version: app dependency pinned to 0.7.1; dx CLI used for this repro was 0.7.9 (3e43ffa)
- Rust version: rustc 1.96.0 (ac68faa20 2026-05-25)
- OS info: Linux Ubuntu kernel 7.0.0-22-generic x86_64
