 | Field | Type | Required | Content type / description | Used for |
 |---|---|---|---|---|
-| `id` | `string` | Yes | Stable slug-like identifier, e.g. `pakket_01`. Currently just an ordinal slug, not a business meaning — reuse as the CMS entry's own key/slug. | React list key + `data-testid` on the card, and referenced in tests. Must be unique and stable across edits (don't regenerate on every content change, or it'll be treated as a different card). |

Must be unique and stable across edits (don't regenerate on every content change, or it'll be treated as a different card). Not rendered on the page. |
+| `slug` | `string` | Yes | Readable, URL-safe identifier derived from `title` (lowercase, hyphen-separated), e.g. `landingspagina`. Unique among offerings; regenerate it when `title` changes, keep it otherwise. | Displayed on the card in place of the raw `id`, so visitors see readable text instead of a GUID. |
 | `title` | `string` | Yes | Short package name (e.g. "Landingspagina"). Plain text, no markup. | Card heading. |
 | `description` | `string` | Yes | One-sentence pitch, plain text. | Subheading under the title. |
 | `price` | `string` | Yes | Pre-formatted price display string — e.g. `"€ 300"` or `"Op maat"` for the quote-based package. **Not a number**: it's rendered verbatim, so formatting (currency symbol, spacing, "Op maat") is the CMS editor's responsibility, not computed client-side. | Large price figure on the card. |
