Detailed Description

std::formatter specialization for Rgba32.

Enables Rgba32 to be used with std::format() and related formatting functions. This makes Rgba32 participate in the FormatParam string conversion chain via the std::formattable concept.

Example usage:

 ++
Rgba32 color{255, 128, 0, 255};
std::string s = std::format("Color: {}", color);  // "Color: [255, 128, 0, 255]"
 
// Works automatically with FormatParam:
FormattableError{"Invalid color: {}", FormatParam{color, Style::bold}};

This is the recommended way to add formatting support for custom types in Porytiles. The formatter delegates to the porytiles::to_string() overload for consistent string representation across the codebase.
