Functions
Value	nk::image::imread (const std::string &path, std::pmr::memory_resource *mr=nullptr)
	Read an image from disk (A = imread(path)).
void	nk::image::imwrite (const Value &A, const std::string &path, std::pmr::memory_resource *mr=nullptr)
	Write an image to disk (imwrite(A, path)).
std::string	nk::image::imwriteToBytes (const Value &A, const std::string &ext, std::pmr::memory_resource *mr=nullptr)
	Encode an image to in-memory bytes (companion to imwrite).
Value	nk::image::imfinfo (const std::string &path, std::pmr::memory_resource *mr=nullptr)
	Read image header metadata without decoding pixels (S = imfinfo(path)).
Value	nk::image::imfinfoFromBytes (const std::string &bytes, const std::string &filename, std::pmr::memory_resource *mr=nullptr)
	imfinfo from already-loaded bytes (the engine entry feeds these from the VFS so it works on the virtual + real filesystem).
Value	nk::image::readTiff (const std::string &path, std::pmr::memory_resource *mr=nullptr)
	Minimal TIFF reader for the formats stb doesn't decode.
Value	nk::image::readTiff (const std::string &path, std::uint32_t page, std::pmr::memory_resource *mr=nullptr)
	Multi-page form: read the page-th IFD (1-based).
Value	nk::image::readTiff (std::vector< std::uint8_t > buf, std::uint32_t page, std::pmr::memory_resource *mr=nullptr)
	Buffer overloads — decode TIFF from already-loaded bytes (the IDE feeds these from the VFS so reads work on the virtual + real filesystem).
std::pair< Value, Value >	nk::image::readTiffWithMap (std::vector< std::uint8_t > buf, std::uint32_t page, std::pmr::memory_resource *mr=nullptr)
std::pair< Value, Value >	nk::image::readTiffWithMap (const std::string &path, std::uint32_t page, std::pmr::memory_resource *mr=nullptr)
	Two-output read for palette TIFFs: returns (indices, colormap).
void	nk::image::peekTiff (const std::string &path, std::uint32_t &W, std::uint32_t &H, std::uint16_t &bits, std::uint16_t &channels)
	Peek a TIFF file's first-IFD metadata without decoding pixels.
void	nk::image::peekTiff (const std::vector< std::uint8_t > &buf, std::uint32_t &W, std::uint32_t &H, std::uint16_t &bits, std::uint16_t &channels)
	Buffer overload — peek metadata from already-loaded TIFF bytes (the IDE feeds these from the VFS so imfinfo works on the virtual + real FS).
std::uint32_t	nk::image::tiffNumPages (const std::string &path)
	Count the number of IFDs (pages) in a TIFF file.
void	nk::image::writeTiff (const Value &A, const std::string &path, const std::string &compression="none", bool appendMode=false)
	Write A to path as a baseline TIFF.
std::vector< std::uint8_t >	nk::image::writeTiffToBytes (const Value &A, const std::string &compression="none", const std::vector< std::uint8_t > *existing=nullptr)
	Buffer form — encode A to a TIFF byte vector (the engine entry writes these through the VFS).
