Mirror the spreadsheet grid in right-to-left layouts: column A on the right, columns flowing leftward, row headers and the vertical scrollbar on the left. All direction logic lives in JS and CSS; the C# render path stays direction-agnostic: - Position cells, headers and overlays with logical insets (inset-inline-start / inset-block-start) instead of transform: translate, so the browser mirrors the grid using the unchanged logical coordinates. - Mirror pointer clientX/offsetX and normalize scrollLeft in JS so the existing C# pointer and scroll math need no changes. - Convert physical CSS (borders, text-align, chevron, validation triangle, resize cursors) to logical properties; flip the merged/active-cell selection mask via a [dir=rtl] rule.
