Functions
std::vector< size_t >	core::application::importing::internal::findAmountTokenIndices (const core::application::importing::transaction::internal::OcrLine &line, int valutaX=-1, int bandPx=0) noexcept
	Finds the indices of amount-like tokens in an OCR line.
std::string	core::application::importing::internal::normalizeAlnumLower (const std::string &s) noexcept
	Normalizes alphanumeric text to lower-case ASCII for matching.
std::optional< int >	core::application::importing::internal::findTokenCenterX (const core::application::importing::transaction::internal::OcrLine &line, const std::string &tokenLower) noexcept
	Locates the horizontal center of a token inside an OCR line.
std::optional< int >	core::application::importing::internal::findPhraseCenterX (const core::application::importing::transaction::internal::OcrLine &line, std::initializer_list< const char * > phraseLower) noexcept
	Locates the horizontal center of a multi-token phrase in an OCR line.
bool	core::application::importing::internal::hasTokenNearX (const core::application::importing::transaction::internal::OcrLine &line, int x, int bandPx) noexcept
	Checks whether any token in the line is close to a horizontal position.
bool	core::application::importing::internal::hasAmountLikeTokenInLine (const core::application::importing::transaction::internal::OcrLine &line, int valutaX) noexcept
	Checks whether the line contains amount-like tokens near the valuta column.
bool	core::application::importing::internal::hasLeftDescriptiveText (const core::application::importing::transaction::internal::OcrLine &line, int valutaX) noexcept
	Checks whether the line contains descriptive text to the left of the valuta column.
bool	core::application::importing::internal::hasAmountNearValuta (const core::application::importing::transaction::internal::OcrLine &line, int valutaX, int bandPx) noexcept
	Checks whether an amount appears close to the valuta reference.
bool	core::application::importing::internal::isLooseTransactionLine (const core::application::importing::transaction::internal::OcrLine &line, int valutaX) noexcept
	Checks whether the line looks like a loosely formatted transaction row.
std::optional< double >	core::application::importing::internal::findAndParseAmountInLine (const core::application::importing::transaction::internal::OcrLine &line, int valutaX=-1, std::vector< std::string > *debugOut=nullptr) noexcept
	Finds and parses an amount token inside an OCR line.
std::vector< core::application::importing::transaction::internal::OcrLine >	core::application::importing::internal::buildOcrLinesFromWords (const std::vector< core::ports::text_recognition::Word > &words)
	Builds OCR lines from raw Tesseract word output.
ColumnGuess	core::application::importing::internal::inferColumnModelFromLines (const std::vector< core::application::importing::transaction::internal::OcrLine > &lines, size_t scanN=16) noexcept
	Infers a column layout from a set of OCR lines.
std::vector< RawLineLite >	core::application::importing::internal::groupMergeLinesRaw (const std::vector< RawLineLite > &lines, int maxGapPx)
	Merges raw lines using a gap-based heuristic.
core::application::importing::transaction::internal::OcrLine	core::application::importing::internal::toOcrLineFromRawWords (const RawLineLite &src, size_t i0, size_t i1) noexcept
	Converts a range of raw words into one OCR line.
core::application::importing::transaction::internal::TransactionMainRow	core::application::importing::internal::splitMainRowFromRaw (const RawLineLite &src, int valutaX, int debitX, int creditX) noexcept
	Splits a raw line into the main transaction row representation.
core::application::importing::transaction::internal::TransactionMainRow	core::application::importing::internal::splitMainRowFromOcrLine (const core::application::importing::transaction::internal::OcrLine &src, int valutaX, int debitX, int creditX) noexcept
	Splits an OCR line into the main transaction row representation.
