Universal Site Announcements 0.6.2 — M6.1: Fixed-row visual styling
- Optional per-fixed-row background, text, link, and border/separator colours for fixed-slot announcements.
- Styling is scoped strictly to fixed announcement rows — rotating notices are unaffected and gain no new controls.
- Absent settings preserve the existing host Store Notice styling exactly as before (zero visual change when unconfigured).
- No changes to AI Multilingual translation, the WooCommerce Store Notice host element, or CPT privacy behaviour; no schema migration.
See docs/closure/m6-1-fixed-row-colour.md for full validation and DEV acceptance evidence.
