/* The editor's own stylesheet: the design tokens, then the page's regions.
 *
 * The token block is OpenCalc's (`webapp/editor.css` at `b23c67c`,
 * webapp/README.md), renamed `--oc-` to `--op-`, with one change: the accent is
 * this product's cyan (`DEC-03`, owner 2026-11-07), `#0e7490`, 5.36:1 on white.
 * `ribbon.tokens.css` aliases its names onto these, so the ribbon follows.
 *
 * The regions are PowerPoint's Normal view: title bar, ribbon, a thumbnail pane
 * on the left, the slide on a grey stage, the notes pane under it, and the
 * status bar. Nothing here names a colour outside the token blocks. */
