   RAZDWA — Chapter rail (lewa sticky sidebar)

   UWAGA: rail jest przenoszony JS-em do <body>,
   bo .project-details-container ma transform i
   tworzy containing block dla position: fixed.

   Założenia (gold standard):
   - desktop: pełna lista 14 rozdziałów widoczna od razu,
     pełne etykiety (bez timeline-kropki), bez scrollowania
     wewnątrz railu w typowym viewport,
   - klik dowolnego rozdziału, w tym środkowego, działa od razu
     (scrollIntoView na targecie w body),
   - rail nie nachodzi na content (sekcja RAZDWA dostaje
     padding-left na ≥1280px) ani na floating prev/next nav po prawej,
   - mobile (≤1100px) — fixed top bar z poziomym scrollem pigułek.
