/* Sdílený vizuální základ Zvol si info pro samostatné nástroje v public/
   (/nomofobie, /anketa). Odkazuje se na něj relativně: ../zsi/zsi.css,
   takže stránky fungují i po dvojkliku z disku, ne jen přes server.

   Proč to není společné i s /ai-test: ten je popsaný v kontext/ai-testik_1/NAVOD.md
   jako balík, který se předává jako jedna složka a otevře se i z file://.
   Má proto vlastní kopii zsi.css a fontů. Když se tady mění barvy nebo fonty,
   je potřeba je změnit i tam.
