/*
 * Landex — design systém pro zákaznický portál a prodejní web (TASK-054 fáze 2).
 *
 * Bez build kroku a bez závislostí: portál i web jsou serverem renderované PHP šablony, takže
 * jeden statický soubor je celá infrastruktura. Světlé téma — u B2B a právních produktů (cookie
 * lišta) působí důvěryhodněji než tmavé.
 *
 * Obsah: 1) tokeny  2) základ  3) layout  4) typografie  5) komponenty  6) pricing  7) licence
