+A powerful web-based text transformation and steganography tool with **222** built-in text transforms spanning encodings, classical and modern ciphers, Unicode styles, formatting, and niche alphabets. Think of it as a universal translator for ALL alphabets and writing systems!
+
+**Version 4.0** brings a redesigned desktop app shell, seven themes (including WCAG 2.1 AA **Accessible**), mobile utility panels, OpenRouter model curation, and responsive UI polish across all tools.
 
 The app is a **static site**: run **`npm run build`** (after `npm install`), then open **`dist/index.html`** in your browser—no local server required. **Alternatively**, you can run it as a local app over HTTP with **`npm start`** or **`npx serve dist -l 8080`** (see [Getting Started](#getting-started) below). Core transforms, decoder, and steganography work **without** calling the cloud; features that use [OpenRouter](https://openrouter.ai/) need **network access** and an API key (see below).

+# Themes
+
+P4RS3LT0NGV3 uses a **token-based theme system**. Most UI reads CSS custom properties (`--accent-color`, `--button-bg`, etc.) from `body.theme-*` blocks, so new themes are mostly palette + typography work—not per-component rewrites.
+
+## Built-in themes
+
+| ID | Name | Notes |
+|----|------|--------|
+| `dark` | Dark | Default; blue accent |
+| `light` | Light | Light surfaces; blue accent |
+| `accessible` | Accessible | WCAG 2.1 AA high-contrast; system fonts; strong focus rings |
+| `bt6` | BT6 | Black + blood red + gold; mono titles |
+| `pliny` | Pliny | CRT green-on-black |
+| `cyberpunk` | Cyberpunk | Magenta + cyan neon |
+| `wildwest` | Wild West | Cream / sage / dusty rose (light `color-scheme`) |
+
+Users pick a theme in **Advanced Settings** (utility dock → Settings tab). Press **`D`** to cycle themes. The choice is saved in `localStorage` under the key `theme`.
+
+## Accessible theme
+
+The **`accessible`** theme targets **[WCAG 2.1 Level AA](https://www.w3.org/TR/WCAG21/)** for color, contrast, focus, and motion.
+
+| Requirement | Implementation |
+|-------------|------------------|
+| **1.4.3 Contrast (AA)** | `#000000` / `#595959` text on `#ffffff`; `#004080` accent; category active colors darkened for white labels |
+| **1.4.11 Non-text contrast** | `2px` borders at `#555555` on inputs, buttons, and cards |
+| **2.4.7 Focus visible** | `3px` `#004080` outline + `2px` offset on all interactive elements |
+| **1.4.12 Text spacing** | `1rem` base size, `1.5` line-height, system UI fonts |
+| **1.4.1 Use of color** | Active nav/tabs use underline + weight + border, not color alone |
+| **2.3.3 Animation** | Logo glitch and decorative card effects disabled |
+| **Transform cards** | Text **Options** / **Favorite** buttons; fixed preview contrast and row heights |
+| **Translation picker** | Text **Favorite** (and **Remove** on custom langs); star/× icons hidden |
+
+Decorative themes (Cyberpunk, Pliny, etc.) are unchanged. For audits, test with the **Accessible** theme selected and keyboard-only navigation.
+
+## How it works
+
+1. **`js/utils/theme.js`** — Registry (`themes` array), `applyTheme()`, `cycleTheme()`, persistence.
+2. **`css/style.css`** — One `body.theme-<id> { … }` block per theme defining design tokens.
+3. **`css/themes-atmosphere.css`** — Optional “premium” overrides for custom themes (nav, transform cards, backgrounds, fonts). Imported at the top of `style.css`.
+4. **`index.template.html`** — Inline bootstrap script applies the saved theme **before** Vue mounts (avoids flash of wrong theme).
+
+When a theme is applied, the body gets:
+
+- `theme-<id>` — primary selector (e.g. `theme-bt6`)
+- `dark-theme` or `light-theme` — legacy aliases still used by a few rules
+
+Copy an existing `body.theme-*` block as a starting point—`body.theme-dark` and `body.theme-light` are the simplest references; custom themes often follow the BT6 / Pliny pattern.
+
+## Adding a new theme
+
+### 1. Register in `js/utils/theme.js`
+
+```javascript
+{ id: 'mytheme', name: 'My Theme', icon: 'fa-star' }
+```
+
+- **`id`** — lowercase, no spaces; becomes `body.theme-mytheme`.
+- **`name`** — label in the dropdown.
+- **`icon`** — optional Font Awesome class (not shown in dropdown today, but kept for future use).
+
+### 2. Add tokens in `css/style.css`
+
+Add a new block (copy from `body.theme-dark` or an existing custom theme):
+
+```css
+body.theme-mytheme {
+    --main-bg-color: #…;
+    --secondary-bg: #…;
+    --nav-bg: #…;
+    --utility-tab-bg: #…;
+    --text-color: #…;
+    --text-muted: #…;
+    --accent-color: #…;
+    --accent-color-rgb: R, G, B;   /* comma-separated, no spaces */
+    --accent-hover: #…;
+    /* … accent-tint-*, surface-*, button-*, input-*, error-*, etc. */
+    --glitch-color: #…;
+    --glitch-color-rgb: R, G, B;
+    --switch-border: #…;
+    --switch-surface-glow: rgba(…);
+    --switch-track-bg: #…;
+    --switch-track-border: #…;
+    --switch-track-checked-bg: #…;
+    --switch-track-checked-glow: rgba(…);
+    --switch-thumb-bg: #…;
+    --switch-thumb-glow: rgba(…);
+    --switch-thumb-checked-bg: #…;
+    --switch-thumb-checked-glow: rgba(…);
+    color-scheme: dark; /* or light for pale themes */
+}
+```
+
+**Required tokens** — At minimum, match what `body.theme-dark` defines: surfaces, text, accent (+ `-rgb`), buttons, inputs, focus/error/success, tooltips, switch tokens, and legacy aliases (`--text-primary`, `--border-color`, etc.) at the bottom of the block.
+
+**Light themes** — Set `color-scheme: light` and ensure `--text-on-accent` contrasts on `--accent-color`. Wild West is the reference for a light custom theme.
+
+**Optional theme tokens** (used by atmosphere CSS):
+
+- `--theme-display-font`, `--theme-ui-font`, `--theme-mono-font`
+- `--theme-secondary`, `--theme-secondary-rgb`
+- `--theme-radius` — corner radius (`0` for sharp, `2px`–`6px` for rounded)
+- Wild West also uses `--theme-cream`, `--theme-charcoal`, etc.
+
+### 3. Optional atmosphere in `css/themes-atmosphere.css`
+
+For a distinctive look beyond color swaps, add a section:
+
+```css
+body.theme-mytheme .app-root::before { /* background texture / tint */ }
+body.theme-mytheme .transform-button { /* card chrome */ }
+body.theme-mytheme .app-nav .tab-buttons button.active { /* nav active state */ }
+```
+
+If you add a custom theme here, also extend the shared selectors at the top of the file (`body[class*="theme-…"]`) so shell layering (`::before` / z-index) stays consistent.
+
+**Style guidelines** (project convention):
+
+- Use **flat colors** only—no CSS gradients unless explicitly requested.
+- Toggle switches (`.switch.neon`) pick up colors from `--switch-*` tokens automatically.
+- Avoid logo `::before` / `::after` decorations.
+
+### 4. Fonts (if needed)
+
+Google Fonts are imported at the top of `css/style.css`. Add families there, then reference them in your `--theme-*-font` tokens.
+
+### 5. Select carets & dropdowns
+
+Custom themes with non-default accents often need a `select` caret override. See existing blocks:
+
+```css
+body.theme-mytheme select:not(.settings-theme-select) { background-image: url("data:…"); }
+body.theme-mytheme .settings-theme-select { … }
+```
+
+Wild West required extra care so theme dropdown carets do not tile—use `background-repeat: no-repeat` and longhand `background-*` when overriding selects.
+
+### 6. Build & test
+
+```bash
+npm run build
+npm test
+```
+
+Open `dist/index.html` (or `npm start`) and check:
+
+- [ ] Advanced Settings theme dropdown lists your theme
+- [ ] **`D`** cycles through it without errors
+- [ ] Nav, main content, utility dock (desktop)
+- [ ] Mobile: utility panel toggle in header; no overlapping FAB
+- [ ] Transform grid, toggles, inputs, notifications
+- [ ] Advanced Settings / OpenRouter model dropdown (if applicable)
+- [ ] Reload persists choice
+
+No change to `index.template.html` is required unless you rename the bootstrap script flow—the dropdown is driven by `themeOptions` from Vue, which reads `ThemeUtils.getThemes()`.
+
+## File checklist
+
+| File | Action |
+|------|--------|
+| `js/utils/theme.js` | Add `{ id, name, icon }` |
+| `css/style.css` | Add `body.theme-<id> { … }` token block |
+| `css/themes-atmosphere.css` | Optional component/atmosphere overrides |
+| `css/style.css` `@import` | Already imports `themes-atmosphere.css` — no change |
+| `README.md` | Add theme to user-facing list (optional) |
+
+## Updating an existing theme
+
+1. Edit the `body.theme-<id>` token block in `css/style.css`.
+2. Adjust matching rules in `css/themes-atmosphere.css` if the theme has premium styling.
+3. Rebuild and spot-check the same checklist above.
+
+Token changes propagate everywhere that uses `var(--…)`; you rarely need to touch individual tools or templates.

-2. Run `npm run build:transforms`
-3. Test in webapp
-4. Add `detector` function if format has distinctive patterns
-5. Optionally add test cases to `tests/test_universal.js`
-6. Add a one-line description for the transform’s `name` in `DESCRIPTIONS` inside `build/readme-transform-section.js`, then run `node build/readme-transform-section.js` and merge the printed block into the **Text Transformations** section of the root `README.md` (the script exits with an error if a transform is missing from `DESCRIPTIONS`)
+1. Place the file in the appropriate category directory (folder name = UI category).
+2. Run `npm run build:transforms` (or `npm run build`).
+3. Test in the webapp (`npm start` → http://localhost:8080).
+4. Add a `detector` function if the format has distinctive patterns (helps the universal decoder).
+5. Optionally add known limitations to `limitations` in `tests/test_universal.js`.
+6. Update the root **README.md**: add or edit a bullet under **Text Transformations** in the matching category section, using the transform’s `name` and a one-line description.
