/* НПО Хелп — the look every tool shares, "Linen & Pine" (apps/DESIGN.md).
   A warm linen page, white surfaces that rest a little above it, pine for the one action that moves
   the work forward, and marigold as the single signature: the current step, the guide's ring, a seal.
   Literata (a letter-like serif) for titles and big numbers, Onest for everything else. Few words:
   explanations live in the on-demand guide (tour.css) and the "Как?" drawer. A tool adds only its own
   screens on top (the letters tool: mail/css/app.css); the block editor's look is builder.css. */
