# Themes Overview

> All built-in Streamly storefront themes — Final packages, how Apply/Preview works, and links to each theme.

Streamly ships **three Final** theme packages under `themes/<id>/`. Switch them in `/admin/themes`. One route tree for all themes — only skins and home templates change.

## Built-in themes

| Theme | ID | Category | Best for |
| - | - | - | - |
| [Streamly](/themes/streamly) | `streamly` | Standard | Default premium OTT (bevel, features) |
| [Streamlix](/themes/streamlix) | `streamlix` | Cinematic | Sharp cinema look, full-bleed |
| [StreamTube](/themes/streamtube) | `streamtube` | Discovery | Guide/rail navigation + search |

## Shared rules

* **Apply** snapshots the previous look into `theme_presets` and restores the target preset/seed — never overwrites SEO/content keys.
* **Preview** with `/?__theme_preview=<themeId>` (operator only, in-memory).
* Chrome isolation via `html[data-storefront-theme="…"]`.
* Zip upload/export UI is hidden (`SHOW_THEME_PACKAGE_IO_UI = false`).
