Pattern Parity Verification

Verify that the canonical background pattern is consistent across all surfaces.

1. Plain Body Background (Inherited)

This area should show the body's canonical background pattern.

Expected: Slate 800 base + radial gradient + orange cross pattern

This simulates the marketing login page container.

Should be transparent, inheriting body background

This area uses the CanonicalPatternSurface wrapper.

Should also be transparent and inherit body background

✓All three swatches display the same background pattern
✓Pattern shows orange cross symbols on slate blue background
✓Gradient is visible at the top (darker slate blue)
✓Text uses three tiers: strong (white-ish), default (slate 300), muted (slate 400)
✓No local background overrides are breaking the pattern
