/* ==========================================================================
   TANKUJ ZDROWO, Sebastian Ratajczyk
   Dietetyk sportowy, dietetyka sportow walki. Poznan i online.

   ===========================================================================
   DESIGN PLANNING PASS (spisany przed kodowaniem)
   ===========================================================================

   CEL STRONY
   Jeden cel: rezerwacja darmowej konsultacji w Calendly. Kazda sekcja konczy
   sie ruchem wzroku w strone przycisku. Dwie sciezki odbiorcy (zawodnik
   sportow walki oraz osoba "cywilna") prowadzone jedna narracja.

   KIERUNEK WIZUALNY
   Zawodnik plus laboratorium. Plakat z gali w polaczeniu z karta wynikow
   badan. Surowa, kondensowana typografia plakatowa niesie energie, monospace
   niesie precyzje danych, ciemne tlo trzyma powage. Kolor akcji wystepuje
   rzadko, wiec kazde jego wystapienie znaczy "kliknij tutaj".

   SIATKA
   Kontener: max 1280px, wewnetrzny margines clamp(1.25rem, 4.5vw, 4.5rem).
   Baza: 12 kolumn, gap clamp(1.25rem, 2.5vw, 2rem).
   Hero: asymetryczny split 1.05fr / 0.95fr, obraz wychodzi poza dolna
   krawedz kadru i poza prawa krawedz kontenera.
   O mnie: 0.85fr / 1.15fr, foto po lewej, tresc po prawej.
   Wspolpraca: wiersze pelnej szerokosci w ukladzie 96px / 1fr / 1.15fr.
   Co otrzymujesz: arkusz specyfikacji, dwie kolumny hairline, jedna na mobile.
   Proces: 4 kolumny na osi poziomej, os pionowa na mobile.
   Efekty: masonry na kolumnach CSS, 3 na desktop, 2 na tablecie, 1 na mobile.
   FAQ: 0.9fr / 1.1fr, naglowek sticky po lewej, accordion po prawej.

   SKALA TYPOGRAFICZNA (ratio okolo 1.33, plynna przez clamp)
   display-1  clamp(2.65rem, 6.6vw, 5.75rem)  Saira italic 900, lh 0.92
   display-2  clamp(2.10rem, 4.1vw, 4.00rem)  Saira Condensed 900, lh 0.95
   display-3  clamp(1.55rem, 1.9vw, 2.40rem)  Saira Condensed 800, lh 1.02
   lead       clamp(1.05rem, 0.4vw, 1.30rem)  Inter 400, lh 1.62
   body       1rem, lh 1.68, max 68ch
   mono       0.75rem, tracking 0.14em, JetBrains Mono
   Tracking display: minus 0.015em. Krój jest juz kondensowany, wiec mocniejsze
   sciesnianie sklejaloby litery.

   RYTM SEKCJI (naprzemienne tla, przedzielone sygnaturowym separatorem SVG)
   nav        transparent, po scrollu ink plus hairline
   hero       ink
   marquee    panel-2, pasek pelnej szerokosci
   o mnie     panel
   wspolpraca ink
   otrzymujesz panel-2
   proces     ink
   efekty     panel
   faq        ink
   cta        ink glebszy, pelnoekranowy
   footer     panel

   ELEMENT SYGNATUROWY
   Zielone linie ruchu: rownolegle, cienkie krzywe w kolorze sage, budowane
   jako inline SVG. Trzy wystapienia i ani jednego wiecej:
   1. hero, szeroka wiazka wychodzaca zza plecow sylwetki, parallax,
   2. separator miedzy sekcjami, wezsza wiazka,
   3. finalne CTA, linie zbiegajace sie w kierunku przycisku.
   Dodatek: miekki rog akcentowy w lewym gornym rogu paneli, uzywany trzy razy.
   Poza tym zero ozdobnikow.

   ZACHOWANIE MOBILNE (projekt od 375px w gore)
   Wszystkie splity skladaja sie do jednej kolumny w kolejnosci narracyjnej.
   Hero: tekst pierwszy, foto pod nim, przyciski pelnej szerokosci, chipy zawijaja.
   Nawigacja: hamburger, pelnoekranowe menu, ogniska klawiatury zamkniete w menu.
   Dolny pasek sticky z jednym CTA pojawia sie po opuszczeniu hero i znika,
   gdy widoczne jest finalne CTA, zeby nie dublowac tego samego przycisku.
   Body dostaje padding dolny rowny wysokosci paska, zeby nic nie bylo zaslonione.
   Proces obraca sie z osi poziomej na pionowa, linia laczaca przechodzi po lewej.
   Efekty schodza do jednej kolumny, dymki zachowuja rozne dlugosci.

   DOSTEPNOSC I RUCH
   Kontrast tekstu na czerni powyzej 4.5:1, focus widoczny na kazdym elemencie
   interaktywnym, accordion i menu opisane przez aria, pelna obsluga klawiatury.
   Reveal on scroll wlacza sie dopiero, gdy JS wystartuje, wiec bez JS tresc
   jest widoczna od razu. prefers-reduced-motion wylacza parallax, marquee,
   rysowanie linii i wszystkie przesuniecia.
