Cultures stop being static one-per-continent blocs. Culture identities are
now stateful: the list is append-only (seeded once at the dawn, schism
children appended later, records frozen after creation) and the
per-settlement culture is mutable state.
- stepCulture(year) in the yearly tick (pure hashes, no RNG):
assimilation (a conquered settlement adopts its ruler's culture, which
drops the Step-5 revolt cultBonus -> assimilation pacifies provinces),
border conversion (population x trade-prestige pressure; realm capitals
exempt), schism (a far-flung coherent cluster -- typically overseas
colonies -- breaks away as a new people with a local-bank NameGen name
and ethos/faith re-derived from its own lands).
- computeCultures() became a pure derived refresh (seeds only when the
list is empty); seedCultures() reproduces the old per-continent peoples
byte-identically for the dawn and pre-v23 loads.
- Colonies inherit the founder's culture at founding; the Step-3
mono-cultural vassalage rule is culture-matched (regionId fallback) so
schism clusters found their own realms -> colonial independence wars.
- Per-cell culture view colours by the owning settlement's culture, so a
conquered city keeps its colour until it assimilates.
- Save v23: culture identities + sSettleCulture + next-id counter, also in
the step-back frames; snapshots rewind via truncate-and-replay. Pre-v23
saves re-seed on the next refresh.
- Kind-7 world events; Cultures tab hides extinct peoples and shows a
schism child's founding year. Knobs cult* in planet.cfg.
- New test_cultevo.cpp (30 checks); all 15 existing suites still pass.

Give the world peoples and faiths on top of Step 3's realms. All derived
deterministically from the (saved) settlement set + geography (pure hashes,
no RNG, recomputed each sim year -> no save-version bump, step-back free).
- PlanetCulture.{hpp,cpp}: computeCultures() groups living settlements into one
culture per inhabited continent, each with a generated people name, a dominant
ethos picked from its cells' environment (Seafaring/Highland/Nomadic/Agrarian,
else a hashed Mercantile/Warlike), and a religion (a Faith focus biased by the
dominant biome + a generated faith name). Runs after computeTerritory().
- Governments: each realm (Nation) gets a GovType from its tier + a deterministic
pick, folded into its name ("Republic of X", "Duchy of X", "X Theocracy", "X
Confederation", "X Dominion", ...) -- culture-driven renaming.
- Culture-driven grouping: realm vassalage is now restricted to the same
continent, so every kingdom/empire is mono-cultural.
- Render: a Culture colour mode (cultureColor, cultural blocs) + pale
buildCultureBorders lines + a Cultures tab + a cell-info culture/faith line +
government-aware realm labels, all under key X. Cultures recompute with
territory in rebuildTerritory().
- test_culture.cpp: one culture per continent, valid ethos/faith, governments per
tier reflected in names, mono-cultural realms, determinism, RNG isolation,
save->load->recompute parity. All 12 suites green.
