Improve Najm example against eval audit

[adewale]

Stacked on #3. Review this PR against pr/tally-eval-audit, not main.

What

Improves the Najm example using the eval audit from #2 while preserving the Moroccan fashion/drop direction.

Targeted changes:

• switches body copy away from overused Inter to Source Sans 3 while keeping Bricolage Grotesque for display
• removes glassmorphism from the sticky nav and product tag
• tokenizes raw OKLCH gradients in product/editorial surfaces
• fixes low-contrast accent-filled badges/buttons detected by the audit
• removes emoji/star glyphs used as decorative feature markers
• changes the cart drawer from a modal dialog role to a labelled region, matching its non-focus-trapping drawer behavior
• fixes skipped footer heading levels
• adds root overflow-x: clip
• keeps announcement content visible on mobile instead of hiding it
• removes rote hover-scale transforms
• adds disabled-state coverage

Why

Najm was another low-scoring real example in the audit. This PR is the second proof-of-value pass: the eval harness can identify concrete, fixable issues in existing examples without requiring a wholesale redesign.

Risk

This touches a visual example, so browser review is still needed. The largest semantic change is the cart drawer role: the drawer was labelled as modal, but the implementation does not trap focus, so role="region" better matches the current behavior.
