   Pravidla, která byla bajtově shodná ve všech stránkách sady. Dřív je každá
   stránka nesla vlastní kopii, takže se úprava vzhledu musela dělat devětkrát
   a devátá stránka na ni zapomněla — přesně tak vznikla past č. 1 v CLAUDE.md.

   Co sem patří: jen to, co je společné celé sadě. Cokoli specifického pro
   jeden nástroj zůstává inline v jeho stránce, kde se to načítá až za tímhle
   souborem, takže to má poslední slovo.
