v1.0.11

Added

• shift({ padding }) now accepts explicit viewport, scroll parent, or custom parent bounds padding.
• Tests covering explicit shift padding, preserved offset-derived padding, and invalid padding sanitization.

Fixed

• shift middleware sanitization now rejects non-finite and negative params.padding values with a deterministic warning.
• Documentation examples using shift({ padding }) now match the public API.
• Arrow docs now clarify that middlewareData.arrow.x/y use the same coordinate space as floating left/top.
• Strategy docs now describe the auto-detected default: fixed for CSS position: fixed, otherwise absolute.
