 * Assumes a **uniform** grid: every column is `colWidthPx` wide and every row is
 * `rowHeightPx` tall (pass overrides for sheets with non-default but uniform
 * sizing). Offsets are always strictly inside their cell, so the result never
 * trips the engine's "offset exceeds the referenced cell" warning. For sheets
 * with per-column/row sizes, derive the anchor from the real layout instead.
