📝 Walkthrough

Walkthrough

Added a blog post for the iX version 6 status terminology and color updates. It covers renamed status levels, ISO and WCAG alignment, the purple Critical severity level, usage guidance, and migration information.

Changes

Status terminology documentation

Layer / File(s)	Summary
Status update blog post blog/2026-09-08-colorchange/index.md	Adds the announcement, status-name mappings, standards and accessibility rationale, purple Critical severity guidance, and migration information.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 9473a

The announcement may be less accessible to screen-reader users and may confuse users migrating status terminology about the meaning of Critical. These are bounded documentation issues that should be corrected before publication.

In `@blog/2026-09-08-colorchange/index.md`:
- Line 12: Replace the generic “banner” alt text on all three images in the
document with meaningful descriptions of the status mapping or Critical
severity; use empty alt text for any purely decorative image.
- Line 27: Update the severity table and related transition text to explicitly
state that v6 reserves Critical for the new purple severity, while the previous
Critical status is renamed to Warning. Preserve the existing severity mappings
and clarify the transition wherever the later Critical section is introduced.
