legacy workaround を避け、semantic HTML / Web Platform Native API / modern CSS の利用機会を提示する。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Goal / 目的

- generic な JS / CSS 実装が「セマンティクスを失った車輪の再発明」になっていないかを検出する。
- semantic HTML / Web Platform Native API / modern CSS の利用機会があれば、より少ないコードで同じ結果が得られる選択肢を提示する。
- 出力は「強制」ではなく「検討してほしい代替案」として suggestion 扱いにする。

## Non-goals / 扱わないこと

- ブラウザ互換性のフル評価(Baseline / Can I Use 表の機械的読み取り)。
- フロントエンドフレームワーク選定や状態管理ライブラリの議論。
- パフォーマンス計測値(LCP / INP)の数値検証。
- 既存コードの大規模リファクタ提案(差分の範囲内のみ)。

## False-positive guards / 抑制条件

- 既に `<dialog>` / `<details>` / `<summary>` などの semantic 要素を使っている箇所は指摘しない。
- ライブラリ提供のコンポーネント (`<Dialog>`, `<Popover>`, ...) は内部実装の選択を尊重し、差分でその利用方法だけが変わった場合は指摘しない。
- 古いブラウザサポート(IE11 / Safari < 15 など)が `.river/rules.md` や README に明示されているリポジトリでは指摘を抑制してよい。
- 差分が typo 修正・rename・import 整理のみで意味的変化を伴わない場合は指摘しない。

## Rule / ルール

### Semantic-first

- click ハンドラ付きの generic 要素 (`<div onClick>`, `<span onClick>`) は、`<button>` / `<a>` / `<label>` などの semantic 要素を検討する。
- ヘッダー / フッター / ナビ / 主要コンテンツ領域は、`role` 属性より `<header>` / `<footer>` / `<nav>` / `<main>` を優先する。
- 開閉可能なコンテンツは custom toggle より `<details>` / `<summary>` の利用を検討する。

### Platform-native API

- modal / dialog 実装では `<dialog>` 要素と `showModal()` / `close()` API を検討する(focus trap / inert / top-layer が無償で得られる)。

How to install

The exact contents, by fingerprint
mdr add s977043/river-review/Modern Web Semantic + Platform-Native@sha256:8a1c28de110d7315

The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
