/* ==========================================================================
   Veřejný web weby.2marsa.cz — výroba webů.

   Od 23. 9. 2026 ve vizuálním jazyce sesterských webů 2marsa.cz a
   design.2marsa.cz (helix-design/assets/style.css): tmavé plochy #0a0d12,
   akcent cyan #00d4d4 → #00a8e8, Inter + JetBrains Mono, ostré hrany (4 px),
   tučná typografie se záporným prostrkáním, kickery v monu, 1px mřížky,
   dlaždice s cyan hoverem, převzatá patička (sitemap + hub + legal modal).

   Tenhle soubor sdílí hlavní stránka a stránky úrovní (/uroven/<slug>/,
   generuje vyrobit-urovne.py). Ukázka Datovna má vlastní styl — je to
   smyšlená firma, ne náš brand; jen lišta úrovní nad ní (_lista/lista.css)
   drží stejné barvy jako tenhle web.

   Písma z Google Fonts stejně jako sesterské weby; bez nich spadne na
   systémová — web kvůli písmu nikdy nespadne.
