GameScene::dibuixar_marges_animat, dibuixar_marcador_animat,
calcular_posicio_nau_init_hud y calcular_progress_rango (4 funciones,
~135 LOC) salen a Systems::InitHud en
source/game/systems/init_hud_animator.{hpp,cpp}.
Las funciones son puras (sin estado interno propio). API libre en
namespace:
- computeRangeProgress(global, init, end): normalizacion de la
ventana de progreso de un elemento dentro del global 0..1.
- computeShipPosition(progress, final_position): interpola Y desde
fuera de pantalla con ease_out_quad.
- drawBordersAnimated(renderer, progress): efecto pincel en 3 fases.
- drawScoreboardAnimated(text, scoreboard_text, progress): texto
subiendo desde abajo.
GameScene inyecta lo que cada funcion necesita por parametro
(spawn point desde obtenir_punt_spawn, scoreboard desde
buildScoreboard). Sin estado mutable compartido.
GameScene.cpp acumulado tras 9a/9b/9c: 1429 -> 1043 LOC.
Smoke test xvfb OK.
