Plain-English definitions of the words used across this documentation, alphabetized.

| Term | Meaning |
|------|---------|
| **Agency** | The white-label parent a group of sites can belong to: its logo, color, and site allowance. Also just: you, the business running the platform |
| **Block** | A ready-made content piece you place in a column, like the NAP card or the HTML embed. See the [Element Reference](/docs/help/element-reference) |
| **Brand DNA** | A site's captured brand: colors, fonts, styles, and reusable component classes, so every page you build stays on-brand. See [Brand DNA](/docs/help/brand-dna) |
| **Build** | Turning content into the finished static files a site serves. Clicking Deploy runs a build |
| **Builder (visual builder)** | The drag-and-arrange editor where you lay out pages from sections, rows, columns, and elements |
| **CMS** | Content Management System - your admin, logins, the portal, and the API. Runs as the cms service on Railway |
| **Custom domain** | The real domain a client site is served on (their own name, not a platform URL) |
| **Deploy** | Publishing a site's built files to the live internet. Deploys are deliberate: you click Deploy; publishing content alone never deploys anything |
| **DNS** | The internet's phonebook, mapping domain names to servers. Set at your domain registrar |
| **Element** | The smallest building unit on a page: a heading, a paragraph, an image, a button |
| **Environment variable** | A named setting or secret the platform reads at runtime. See [env-vars](/docs/help/env-vars) |
| **Media library** | A site's uploaded images and files, stored durably in R2 and scoped per site |
| **Migration (database)** | A change to the shape of the database, run once when updating versions. See [Updating](/docs/help/updates) |
| **Migration / port (site)** | Reproducing an existing live website inside the builder so a client can move onto your platform. See [Port a Site](/docs/help/port-a-site) |
| **Operator** | You: the login that manages every client site on the platform |
| **Pages (Cloudflare Pages)** | Cloudflare's static hosting. Each client site is one Pages project |
| **Parity** | How closely a ported page matches its source, measured by the migration pipeline's checks |
| **Pixl** | The Seedly Sites hedgehog, and the guided setup companion you run with `npx pnpm run setup` |
| **Publish** | Marking content live in the CMS. A published page is ready for the next deploy, but publishing by itself changes nothing on the live site |
| **R2** | Cloudflare's file storage; holds the images clients upload |
| **Railway** | The service that runs the platform: the cms service, Postgres, and the studio |
| **Row / Column** | The layout grid inside a section: rows hold columns, columns hold elements. See [Rows & Columns](/docs/help/rows-columns) |
| **Saved block / preset** | A section you saved for reuse, or one of the built-in section presets. See [Presets & Saved Blocks](/docs/help/presets-saved-blocks) |
| **Section** | A full-width horizontal band of a page, and the top of the layout hierarchy. Pages are stacks of sections |
| **Static site** | A site served as pre-built HTML, CSS, and images, with no server code at request time. Fast by construction, and portable |
| **Studio (pagebuilder)** | The service that serves the visual builder and page preview; the CMS proxies to it in production |
| **superAdmin** | The operator-level permission that sees and manages everything on the platform. See [Users & Roles](/docs/help/users-roles) |
| **Tenant** | One client's website inside your platform: its pages, blog, media, settings, and domain. You can host many |
| **The doctor** | The readiness check, `npx pnpm run setup:check`. Reports READY or NOT READY and names any gaps |
| **Tracking script** | A third-party snippet (like GA4) added to a site under its Tracking tab |
