/* The website's look: the brand is the kit, so these are the kit's own values, copied.
   - The tokens: packages/ui/src/shell/shell.css, `:root` (the dark look) and `:root[data-theme="light"]` (the light
     look), only those the page uses, each by its own name; the look follows the visitor's setting.
   - The start screen's icon tile, name, line and presses: packages/parts/src/first-run/first-run.css (.appicon, .word,
     .welcome .sub, .b), as Welcome draws them.
   - The sheet: packages/ui/src/kit/kit.css (.k-sheet, .k-sh-hd, .k-sh-body, .k-sh-ft, .k-x, .k-btn); its body as the
     design page's FirstTimeSteps (apps/design/src/pages/website.proposed.tsx).
   No blue: what the page presses and lights is the ink. */
