/* tokenteger — ransom-note design.
   Layout: full-height app frame (topbar / workspace / statusbar); the grid
   scrolls inside #viewport with an address gutter per row and a VS Code-style
   minimap rail on the right. Square corners everywhere.
   Token pieces are drawn as straight "scraps" in shades of one gold family —
   the shade steps (plus a hairline border and a gap) mark where each token
   starts and stops. Cell text is the raw digits only, so browser find (Ctrl+F)
   matches numbers like "10000"; commas and piece boundaries are CSS-only. */
