ConstThe live counterpart of CellTextRenderer's (plain) showFormulas path: the tiled layer keeps
every formula cell as an immutable plain-text snapshot, and SheetCellLayer suppresses the
ANCHOR cell (the live data-rc CSS channel) and overlays this renderer in its place — so
selection moves never invalidate a tile. Colors are emitted as theme tokens (light-dark()
aware), so a mode flip re-resolves in pure CSS here too.
Layout mirrors the plain formula path's rules: forced left alignment, no rotation, no overflow past the cell box (clipped by the hosting box), the vertical position from the SDK placement, and the letter-spacing that paints the text at its measured width. (2nd pass: hover highlight/eval tooltips like the editor's overlay.)
The formula-view cell renderer: the anchor cell's formula as tokenized, syntax-colored text.
