+I will implement the requested changes across four files to handle localization, UI styling, and metadata updates.
+
+### 1. Localization for Game Options
+**Files**: `public/src/js/strings.js`, `public/src/js/songselect.js`
+- **Action**: 
+  - Add a new `customSettings` section to `strings.js` containing translations for:
+    - "Speed" (ばいそく)
+    - "Invisible" (ドロン)
+    - "Reverse" (あべこべ)
+    - "Random" (でたらめ)
+    - "Sort by Title" (タイトル順で並べ替え)
+    - Associated prompt messages (e.g., "Enter speed multiplier").
+  - Update `songselect.js` to replace hardcoded Japanese strings with references to these new `strings` properties, ensuring the menu text updates dynamically based on the selected language.
+
+### 2. Beautiful Category Colors
+**File**: `tools/categories.json`
+- **Action**: Refine the `song_skin` colors for each category to ensure they are distinct, aesthetic, and visually pleasing.
+  - **Pop**: Cyan/Blue (`#219fbb`)
+  - **Anime**: Vibrant Orange (`#ff9700`)
+  - **Vocaloid**: Miku Green/Teal (`#39c5bb`) - *Adjusted for better recognition*
+  - **Variety**: Lime Green (`#8fd321`)
+  - **Classical**: Elegant Gold (`#d1a016`)
+  - **Game Music**: Deep Purple (`#9c72c0`)
+  - **Namco Original**: Reddish Orange (`#ff5716`)
+
+### 3. Version and Metadata Updates
+**File**: `templates/index.html`
+- **Action**:
+  - Update version text from `vLightNova 1.0.0` to `vLightNova 1.0.1`.
+  - Update the year in the description meta tag to `2026`.
+  - Optimize the `<meta name="keywords">` tag by adding more relevant terms (e.g., "web game", "simulator", "taiko no tatsujin web") and organizing existing ones.
+
+### 4. Verification
+- **Action**:
+  - Verify that the game options menu displays the correct language text (English/Japanese/Chinese/etc.).
+  - Verify that the category backgrounds appear with the new color palette.
+  - Check the page source to confirm the version number and meta tags are updated.
