Hey - I've found 1 issue, and left some high level feedback:

• Consider correcting the typo in the changelog entries (e.g., "Order alphatically" → "Order alphabetically" and "conformsTO" → "conformsTo") for better readability.
• Names in the changelog are inconsistently capitalized (e.g., @Hans-christian vs @Hans-Christian); aligning these to a single, correct form will make the log more consistent.

## Individual Comments

### Comment 1
<location path="CHANGELOG.md" line_range="39" />

+### Removed
+- remove !important by @Hans-christian in 9044fcc
+- Order alphatically and remove duplicate conformsTO by @Hans-christian in 7230e01

</code_context>
<issue_to_address>
**issue (typo):** Fix spelling of "alphabetically" and casing of "conformsTo".

These changes will align the wording with earlier usage and standard camelCase conventions.

Suggested implementation:

```
### Removed
- remove !important by @Hans-christian in 9044fcc
- Order alphabetically and remove duplicate conformsTo by @Hans-christian in 7230e01

```

If the `Order alphatically and remove duplicate conformsTO` entry is not yet present under `### Removed` in `CHANGELOG.md` (because the snippet you shared only showed the first bullet), add the corrected version directly:
- `- Order alphabetically and remove duplicate conformsTo by @Hans-christian in 7230e01`
</issue_to_address>
