/**
 * textLoader — plain text, decoded and left alone.
 *
 * Pattern: Adapter behind `DocumentLoader`.
 * Role:    rag/ layer. The simplest possible loader, and the one that defines
 *          what "leaving positions alone" means for the others: it decodes
 *          UTF-8, normalises line endings, and does nothing else. No trimming,
 *          no collapsing of blank lines, no smart quotes — every one of those
 *          would shift every offset after it, and an offset that does not
 *          index the original is worse than no offset at all.
 * Emits:   N/A.
 *
 * Line-ending normalisation is the one exception, and it is a deliberate one:
 * `\r\n` → `\n` happens BEFORE any offset is computed, so offsets index the
 * normalised text, which is also the text that is stored and shown. The
 * alternative — keeping `\r` — makes every paragraph boundary two characters
 * on Windows and one everywhere else, so the same document chunks differently
 * depending on who checked it out.
