/*
 * The diff page (diff.html). Loaded after styles.css and auth.css, whose app
 * shell, header, buttons and dialog styles it builds on — not pages.css, whose
 * body line-height and scrolling body fight the full-height app shell.
 *
 * Severity colours reuse the editor's token palette so a diff reads as the same
 * product: green = --json-string (added), red = --json-null (removed), amber =
 * --json-number (changed), purple = --json-boolean (type). Search hits are a
 * blue RING, never the editor's amber fill, which would vanish on an amber row.
 *
 * The panes use white-space: pre and a fixed 22px row, so left and right rows
 * line up by CSS alone — no measuring, no ResizeObserver.
