@@ -528,3 +528,203 @@ Aktualizacja materiałów powierzchni (18.10.2026):
   umieszczenia budynków na mapę, brak rzek i zoom powierzchni 0,8.
 - Nowe tekstury wygenerowano wbudowanym imagegen. Pliki i komplet promptów:
   assets/planets/terrain/ oraz assets/planets/terrain/prompts.json.
+
+Drobne dekoracje przyrody (18.10.2026):
+- Dodano atlas PNG z 16 grafikami: iglak, brzoza, dąb, suche drzewo,
+  otoczaki, granit, omszałe skały, drobny żwir, krzew, paprocie,
+  kwiaty, sucha trawa, powalone drzewo, pień, grzyby i trzciny.
+- Dotychczasowe drzewa pozostają częścią lasów. Nowe gatunki i runo
+  dobierane są do sześciu krajobrazów; trzciny rosną przy brzegach,
+  suche trawy dominują w suchym i chłodnym klimacie.
+- Generator próbuje rozmieścić 150 niewielkich skupisk po 2–5 detali.
+  Woda, góry i polany ograniczają ich ostateczną liczbę.
+- Powalone drzewo: 8% szansy próby na leśnej mapie (krajobrazy 0–3),
+  najwyżej jeden egzemplarz, jeśli znajdzie się suche miejsce w pobliżu lasu.
+- Dekoracje omijają lądowisko, POI, zabudowania i pytajniki wydarzeń.
+  Są wyłącznie wizualne; nie zmieniają kolizji, nagród ani zasad eksploracji.
+- Osobny strumień losowania detali zachowuje dotychczasowe rozmieszczenie
+  POI, budynków i wydarzeń dla tego samego ziarna mapy.
+- Grafika: wbudowany imagegen. Atlas i pełny prompt:
+  assets/planets/nature/nature_atlas.png oraz prompts.json.
+- Weryfikacja: render sześciu krajobrazów, powtarzalność generatora,
+  wolne miejsca interakcji oraz limit powalonych drzew w 240 próbach.
+
+Korekta stabilności detali podczas ruchu (18.10.2026):
+- Włączono generowanie mipmap dla nature_atlas.png. Powierzchnia używa
+  filtrowania liniowego z mipmapami; atlas wcześniej nie miał tych poziomów,
+  co powodowało migotanie drobnych detali przy pomniejszeniu i ruchu kamery.
+
+Skala obiektów i rzadkie ślady krajobrazu (18.10.2026):
+- Dekoracyjne budynki zmniejszono o 35%. Grafiki kopalń i ruin POI również
+  zmniejszono o 35%; podpisy przesunięto bliżej. Złoża zachowują skalę.
+- Drzewa zmniejszono o 20% (rozmiar 52–92); powalony pień z 115 do 92.
+- Dodano pięć osobnych grafik: rozgałęzione pęknięcie ziemi, stary krater
+  z fragmentem meteorytu, opuszczoną osadę czterech domków, zwietrzały
+  krąg kamieni i wyschnięte oczko wodne z gliniastym dnem.
+- Szanse próby umieszczenia na mapie: pęknięcia 55% (1–3), krater 14%,
+  osada 6%, kamienie 12%, wyschnięte oczko 30% w krajobrazach 3–5
+  i 12% w krajobrazach 0–2. Poza pęknięciami najwyżej jeden danego rodzaju.
+- Powstają tylko na suchych parcelach, poza lądowiskiem, wodą, górami,
+  istniejącą zabudową, POI i wydarzeniami. Drzewa, skały i runo nie
+  zasłaniają nowych dekoracji. Brak odpowiedniego miejsca pomija obiekt.
+- To ozdoby bez interakcji i nagród. Generator ma osobne ziarno losowania;
+  nie dodaje nowych wydarzeń, przeciwników ani wymagań eksploracji.
+- Wszystkie nowe grafiki korzystają z mipmap i filtrowania liniowego,
+  aby ograniczyć migotanie podczas przesuwania kamery.
+- Grafiki: wbudowany imagegen. Pliki i pełne prompty:
+  assets/planets/landmarks/ oraz assets/planets/landmarks/prompts.json.
+- Weryfikacja tej aktualizacji: test 240 map (wszystkie pięć rodzajów ozdób,
+  odstępy i suchy teren), test przyrody w sześciu biomach oraz render
+  pięciu dodatków i porównania skali. Potwierdzono mipmapy i przezroczystość
+  każdej nowej tekstury. Podgląd: artifacts/landmarks_overview.png.
+
+Dziesięć wydarzeń fabularnych na powierzchni (18.10.2026):
+- Zastąpiono poprzednie spotkanie z inżynierem katalogiem dziesięciu
+  wydarzeń z zatwierdzonymi opisami i odmiennym przebiegiem.
+- Na mapie jest 50% szansy próby umieszczenia jednego znaku zapytania.
+  Dziesięć rodzajów ma jednakową wagę. Miejsce musi być suche, poza
+  górami, lądowiskiem, zabudową i POI. Pozostałe 50% nie ma wydarzenia.
+- Zachowano automatyczne otwarcie przy 180 jednostkach, ponowne uzbrojenie
+  po oddaleniu ponad 260 oraz ręczne otwarcie klawiszem F.
+- Rodzaje: Wędrowny handlarz; Wymiana towarów; Kolekcjoner minerałów;
+  Kontener w ciemno; Płatny skan skrytki; Pewna wypłata albo ryzyko;
+  Test prototypu; Akcja ratunkowa; Ewakuacja etapami; Mobilny serwis.
+- Oferta i ukryty łup są przygotowywane raz. Zamknięcie okna nie odświeża
+  nagród, prób ani cen. Zrealizowane spotkania są zużyte; skan i ewakuacja
+  pamiętają etap także po zamknięciu okna.
+- Handlarz: wybór jednej z trzech ofert. 3–6 rakiet kosztuje 70% ceny
+  sklepowej całego pakietu, po rabacie kapitana. Pozostałe oferty to
+  8 miedzi i 8 krzemu za bazowo 70 kredytów/poziom układu albo znany
+  moduł za bazowo 140 kredytów/poziom, z widocznymi parametrami w podpowiedzi.
+- Wymiana: 12 żelaza i 4 miedzi na 8 niklu lub 6 żelaza, siarki i uranu
+  na 3 rakiety. Kolekcjoner płaci 120 kredytów/poziom za 6 sztuk
+  wylosowanego surowca planetarnego.
+- Kontener: bazowo 100 kredytów/poziom. Skan: 15 kredytów/poziom, a potem
+  osobno 75 za otwarcie. Skan ujawnia grupę łupu, bez ilości i parametrów.
+- Tajemniczy łup: 50% na 2–8 części, 35% na 6–15 sztuk jednego z pięciu
+  materiałów planetarnych, 10% na 2–4 rakiety, 5% na moduł statku.
+  Moduły mają poziom układu + geometryczny bonus 0–20, z maksimum 1000;
+  szczęście kapitana nie podnosi tego limitu. Brak sprzętu kapitana w łupie.
+- Wybór pewny/losowy: ta sama bazowa cena 80 kredytów/poziom; gracz wybiera
+  gwarantowane 6 części albo tajemniczy pakiet z powyższej puli.
+- Prototyp: gwarantowane 35 kredytów/poziom, premia za sukces dodatkowo
+  90 kredytów/poziom i moduł. Szansa to pierwszy etap POI minus 10 pp;
+  porażka zadaje 12–20 HP plus do 10 HP za trudność planety.
+- Ratunek: koszt 6 części; sukces daje 140 kredytów/poziom i 8 części.
+  Szansa jak pierwszy etap POI; porażka 8–16 HP plus do 10 za biom.
+- Ewakuacja: trzy etapy ze szansami POI po sprzęcie i warunkach. Koszty
+  2/3/4 części, wypłaty 40/70/110 kredytów/poziom i 2/4/6 części.
+  Po każdym sukcesie można zakończyć albo kontynuować. Porażka kończy
+  wydarzenie i zadaje 8–16 HP + 4 za indeks etapu + do 10 za biom,
+  ale nie zabiera wcześniejszych nagród. Nie ma zapłaty za nieudany etap.
+- Serwis: jednorazowa naprawa do 25 HP, ograniczona do brakującego kadłuba;
+  cena bazowo 4 kredyty za HP i poziom układu. Brak opłaty przy pełnym HP.
+- Ceny zakupów za kredyty uwzględniają rabat kapitana. Koszt i ewentualne
+  ryzyko są widoczne przed decyzją; brak zasobów wyłącza przycisk i jest
+  ponownie sprawdzany w logice transakcji.
+- Koszty pobierane są od razu, najpierw z tymczasowego łupu, potem z zasobów
+  kapitana. Kredyty, części, rakiety, minerały i moduły zdobyte na powierzchni
+  pozostają tymczasowe do bezpiecznego powrotu. Zniszczenie usuwa nowy łup,
+  nie zwraca wydatków i zachowuje wcześniejszy majątek.
+- Rakiety po powrocie trafiają do amunicji statku, części do części kapitana,
+  kredyty do portfela. Pełna ładownia nadal pozostawia moduły we frachtowcu.
+  Rozliczenie i odbiór nie duplikują nagród.
+- Dialog ma przewijanie, opis fabularny, koszty, jawne nagrody oraz szansę
+  i zakres obrażeń przy ryzyku. Zniszczenie używa tego samego efektu co POI.
+- Testy: komplet 10 zdarzeń i transakcji, 501 wydarzeń w 1000 prób na
+  dostępnym terenie, sukces/porażka, wieloetapowość, odmowy i brak środków,
+  zachowanie stanu po ponownym otwarciu, łup przy powrocie i zniszczeniu,
+  faktyczne przekazanie rakiet statkowi oraz render wszystkich dialogów.
+- Podgląd: artifacts/events_overview.png. Źródło opisów i parametrów:
+  scripts/planets/surface_events.gd.
+
+Korekta poziomów modułów z wydarzeń (18.10.2026):
+- Moduł może mieć każdą normalną jakość lootu, od zwykłego do legendarnego.
+  Używa generate_for_definition z tierem 0, bez wymuszenia lepszej rzadkości.
+- Bonus poziomu modułu z wydarzenia ograniczono do +0..+10 ponad poziom
+  układu. Wagi wynoszą 0,65^k, normalizowane dla 11 możliwych wyników.
+  Szansa maleje wykładniczo wraz z bonusem. Nie ma kumulacji ogona na +10.
+- Zachowano maksimum poziomu 1000. Szczęście nie przekracza limitu +10.
+- Korekta dotyczy wszystkich modułów z wydarzeń, także ofert handlarza
+  i premii za prototyp. Standardowy loot i nagrody POI zachowują swoje zasady.
+- Test: 100000 losowań poziomu oraz 1000 modułów z kontrolą jakości,
+  zakresu poziomów i limitu 1000.
+
+Wspólne skalowanie nagród według biomu (18.10.2026):
+- Zasady w scripts/planets/planet_rewards.gd obowiązują moduły zarówno
+  z wydarzeń, jak i z POI, łącznie z ofertami handlarza i prototypem.
+- Premia poziomu ponad poziom układu: biom łatwy (trudność 0) +0..+2,
+  średni (0,5) +1..+6, najtrudniejszy (1) +2..+10. Pomiędzy nimi granice
+  zmieniają się płynnie: minimum round(2*d), maksimum round(2+8*d).
+- W obrębie zakresu wagi kolejnych bonusów wynoszą 0,65^k, normalizowane
+  do liczby dostępnych poziomów. Dolna granica jest najczęstsza, górna
+  najrzadsza. Maksymalny poziom przedmiotu pozostaje 1000.
+- Dodatkowe etapy POI oraz szczęście nie podnoszą poziomu ponad zakres
+  biomu. Zachowano dotychczasowe zasady jakości: zwykłe losowanie dla
+  wydarzeń, istniejącą premię jakości trudnych/głębokich POI.
+- Minerały, materiały planetarne i części otrzymują mnożnik 1+2*d,
+  czyli ×1 / ×2 / ×3. Dotyczy również skrzyń, gwarantowanego zestawu,
+  paczek handlarza, wymiany minerałów, ratunku i nagród etapów ewakuacji.
+  POI zachowują dodatkowy mnożnik ilości za głębszy etap.
+- Wyraźnie wykluczono z mnożnika rakiety, amunicję zwykłą i radiacyjną,
+  inne przedmioty użytkowe oraz kredyty. Ilość rakiet pozostaje taka sama:
+  3–6 u handlarza, 3 w wymianie, 2–4 w tajemniczym pakiecie.
+- Cena pakietu rakiet po rabacie kapitana: 70% ceny sklepowej na łatwym,
+  60% na średnim i 50% na najtrudniejszym biomie. W wymianie 3 rakiet
+  koszt żelaza, siarki i uranu maleje z 6 przez 5 do 4 sztuk każdego.
+- Koszty innych decyzji, wypłaty kredytów, szanse powodzenia i obrażenia
+  zachowują dotychczasowe zasady. Skala materiałów nie mnoży kosztów.
+- Premie widać w dialogach wydarzeń i POI; jawna oferta pokazuje faktyczną
+  ilość po skalowaniu. Nagrody są skalowane tylko raz.
+- Testy: 30000 losowań bonusu poziomu w trzech biomach, 3600 prób POI,
+  600 porównań tajemniczego łupu; stałe ilości amunicji, niższe ceny
+  rakiet, pełny zakres poziomów, limit 1000 i brak podwójnego mnożenia.
+- Dodatkowo przeszły testy wszystkich dziesięciu wydarzeń, pełnego powrotu
+  z wyprawy oraz render dialogów na najtrudniejszym biomie.
+  Podgląd: artifacts/hard_events_overview.png.
+
+Globalne zagrożenie i ochrona kapitana (18.10.2026):
+- Zastąpiono poprzednie kary i dodatkowy bonus poziomów nowym wskaźnikiem.
+  Trzy zagrożenia mają osobno zakres 0–100%, suma wynosi 0–300%.
+- Tlen: brak zagrożenia przy co najmniej 80%; rośnie liniowo do 100%
+  zagrożenia przy 0% tlenu. Wartość jest ograniczona do zakresu 0–100%.
+- Temperatura: bezpieczny przedział −10..+40°C. Mróz −50°C i upał +100°C
+  dają po 100% zagrożenia termicznego; oba kierunki rosną liniowo.
+- Zagrożenie biologiczne: wartość 0..50 odpowiada 0..100% zagrożenia.
+- System oddychania odejmuje 2 punkty procentowe zagrożenia tlenu za każdy
+  swój poziom; skafander tak samo temperaturę, broń ręczna biologię.
+  L1 daje już 2 pp ochrony, L25 daje 50 pp, L50 daje 100 pp. Ochrona
+  działa tylko na własną składową, nie przenosi nadwyżki na inne.
+- Globalny wskaźnik jest sumą pozostałych trzech zagrożeń po ochronie.
+  Nie może spaść poniżej 0. Usunięto dawny bonus +0,4 pp do szans za poziom.
+- Szanse etapów POI: przy zagrożeniu 0% wynoszą 90% / 70% / 40%.
+  Maleją liniowo do 15% / 5% / 0% przy zagrożeniu 150%. Od 150% do 300%
+  pozostają na tych wartościach. Przykład dla 75%: 52,5% / 37,5% / 20%.
+- Średnia szansa pokazywana przed lądowaniem to średnia arytmetyczna
+  trzech etapów, a nie szansa przejścia wszystkich etapów naraz.
+  Daje 66,7% przy zagrożeniu 0% i 6,7% przy zagrożeniu co najmniej 150%.
+- Skan pokazuje warunki, każdą surową składową i wynik po sprzęcie, sumę
+  globalną, średnią i trzy szanse POI oraz koszt wejścia w atmosferę.
+  Wartości są przeliczane dla aktualnie założonego wyposażenia.
+- Powierzchnia i dialogi również pokazują globalne zagrożenie po sprzęcie.
+  Podpowiedzi przedmiotów oraz warsztat opisują nową ochronę 2 pp/poziom.
+- Ryzykowne wydarzenia '?' korzystają z tego samego wskaźnika: ratunek
+  z pierwszego etapu, ewakuacja z kolejnych etapów. Prototyp zachowuje
+  dodatkowe −10 pp szans: 80% bez zagrożenia, 5% od zagrożenia 150%.
+  Zniesiono dawne minimum 8%, aby decyzja mogła rzeczywiście mieć 0%.
+- Próby z zerową szansą są wyłączone w UI i odrzucane w logice bez
+  kosztu, obrażeń, zamykania miejsca ani zmiany losowania POI.
+  Zakończenie pomocy i powrót do lotu pozostają dostępne.
+- Bezpieczne transakcje handlowe nie otrzymują losowej szansy porażki.
+- Premie materiałów i poziomów modułów nadal bazują na rzeczywistych
+  warunkach planety przed ochroną. Sprzęt nie zmniejsza nagrody biomu.
+  Surowa trudność to suma trzech zagrożeń podzielona przez 300.
+- Koszt wejścia w atmosferę i zakres obrażeń po niepowodzeniu nadal
+  wynikają z surowej trudności; ochrona wpływa na szansę uniknięcia porażki.
+- Testy: zakres 0..300, oba skrajne kierunki temperatury, neutralne warunki,
+  niezależność trzech slotów, L1/L25/L26/L50, ciągłość i próg 150%, pełna
+  neutralizacja, średnia skanu, ryzyko wydarzeń i brak opłaty przy 0% szans.
+  Przeszły też regresje wydarzeń, skalowania łupu, wypraw i panelu skanu.
+- Zweryfikowano render skanu bez zagrożenia, przy 150% i po ochronie L50,
+  a także blokadę trzeciego etapu kopalni oraz ewakuacji.
