Pull request overview

This PR makes float parsing and serialization culture-invariant in several core math and serialization utilities, and cleans up a few encoding/typographical issues in comments and third-party headers.

Changes:

• Standardizes string and float conversions in Sandbox.System to use CultureInfo.InvariantCulture or FormattableString.Invariant, covering translation utilities, serialized properties, and RangedFloat.
• Updates vector/rotation/angles Parse methods to use invariant culture to match other math types and parsing utilities.
• Fixes mis-encoded characters and punctuation in comments and copyright headers, and clarifies simplification method summaries.

File	Description
engine/Sandbox.Test.Unit/UI/Styles/StyleSetting.cs	Fixes an apostrophe encoding issue in a CSS transition unit test comment.
engine/Sandbox.System/Translation.cs	Makes string conversions and float parsing invariant-culture, aligning translation/conversion behavior with culture-independent expectations.
engine/Sandbox.System/SerializedObject/SerializedProperty.cs	Uses invariant culture when converting arbitrary values to strings in serialized properties.
engine/Sandbox.System/Math/Vector4.cs	Updates Vector4.Parse/TryParse default path to use invariant culture, matching other math types’ parsing behavior.
engine/Sandbox.System/Math/Rotation.cs	Routes default Rotation.Parse/TryParse calls through invariant-culture parsing for consistent numeric handling.
engine/Sandbox.System/Math/RangedFloat.cs	Uses invariant culture for parsing optional floats and for ToString, ensuring round-trippable, culture-independent range serialization.
engine/Sandbox.System/Math/Angles.cs	Updates Angles.Parse/TryParse default behavior to use invariant culture, consistent with other math parsing helpers and tests.

Here we’re using the float.TryParse(string, IFormatProvider, out float) overload, whereas the rest of the codebase generally uses the explicit NumberStyles.Float + provider overload for culture‑invariant float parsing (for example, Math/Length.cs and Utility/Parse.cs). For consistency with existing parsing behavior and to avoid any subtle differences in accepted formats, consider switching this to the float.TryParse(string, NumberStyles.Float, CultureInfo.InvariantCulture, out var f) pattern used elsewhere.

Suggested change

	if ( float.TryParse( from.ToString(), CultureInfo.InvariantCulture, out var f ) )
	if ( float.TryParse( from.ToString(), NumberStyles.Float, CultureInfo.InvariantCulture, out var f ) )

These are good changes, but you've touched and committed so many irrelevent files.

Looks like dotnet format touches them. It apparently changes encoding of these files from windows-1252 to windows-1250. In what encoding these should be saved anyway?
