战斗舞台背景 · 分层生图提示词卡 v1.10
性质：B 区战斗舞台背景（顶部空区＋远景天然洞壁＋近景连续泥土地面＋分隔带）的出图执行侧文件。背景按三关出三张变体，地面三关共用一张；场景级资产，与角色级 art-prompts 并列，两文件互不覆盖。 依据：场景构成与图层归属 = art-bible §6.1；三关方向 = art-bible §6.3；色板 = art-bible §4.1（战斗屏场景环境子板）；尺寸 =
game/data/tables/battle_layout.tres（背景读stage_h；地面读ground_h，字段值 100）；命名与路径 = asset-path-map；后处理 = art-pipeline-tools。 边界：只管三张背景变体与一张共用地面的提示词与验收；角色、格面、图标、小石台scene_stage_plaza.png与样张走 art-prompts 与脚本管线，不在本卡。 建立：2026-10-31 · 状态：三关背景变体与共用地面已按本工单出图并入包（选定＝dungeon v10c／underdark v10c／deep_underdark v10c／ground v12b，落点与读数见 art-bible §6.1「B 区舞台背景与共用地面的交付绑定」）；出图通道由作者自定（参考候选可用内置 ImageGen，水印可留；入包终稿须干净）。
0. 使用流程（四步）
- 出图：按 §2 把提示词贴进生图渠道；每次出图先放 §1 的风格参考图。先只出 dungeon 背景 1 张，作者确认风格前缀后，再出 underdark / deep_underdark 两张变体与连续地面层。
- 入库：候选原图放
artwork/candidates/scene_stage_bg/（三关变体用dungeon_*/underdark_*/deep_underdark_*命名）与artwork/candidates/scene_stage_ground/；_登记.txt记用途与生成时间。 - 后处理：三张背景不去底（不透明全幅）；连续地面层去底转透明（顶缘以上键控）＋最近邻降采样＋色板量化＋底测试条；工具清单与已知边界见 art-pipeline-tools。
- 转正：终稿转入
game/assets/art/scene/；三张背景按board_type选图、连续地面层接线与布局表ground_h字段均已实装落码。
1. 风格参考图（每次出图都要带）
| 参考图 | 作用 |
|---|---|
game/assets/art/character/character_hero_idle.png |
定像素密度、平涂质感、描边与暖色族 |
game/assets/art/board/terrain_floor_dungeon_1.png |
定岩面/地面的笔触与色族；只借质感，不抄瓦片形状与拼块接缝 |
game/assets/art/scene/scene_stage_plaza.png |
定近景层色族与顶缘处理；只借色与像素密度，不借石板铺装 |
禁止拿未经验证的自造图当风格参考——风格错了整批全废。元素参考可用 D&D 洞穴/地下城的岩层、裂缝、凹壁、碎石等常见构成（见 §3），但不把外部图当风格锚。
贴参考图时，在提示词末尾接这一句：
Style reference: the attached images are this game's own finished pixel art — match only their rendering style, the same pixel density, flat shading, hard edges and warm limited palette. They are style references only: do not copy their subjects, characters, gear, props, tile patterns or any specific rock or ground layout, and do not put any character into the scene.
2. 两层提示词
2.1 背景层（三关变体，按 board_type 选一张）
画什么：顶部空区（深色、无物）；纵深洞厅远景——远层暗剪影（远处洞口/通道、层叠岩体、洞底轮廓）、中层主要细节层（岩台、岩柱、凹壁、裂缝、建筑剪影）、近层左右暗色岩框；三关母题按 §3.2。 不画什么：近景地面、地台、平台；贴墙感、单件圆柱/贴图直接贴顶、悬挂物；砖石墙、规则砌缝、方整石块、瓷砖/铺装；钟乳石、吊锥、洞顶结构；角色、生物、道具、火把/灯/发光物；文字/UI。

共用底座正向提示词（三张共用）：
Pixel art style. True pixel art game background layer drawn with chunky square pixels, strict pixel grid alignment, hard edges, no anti-aliasing, no gradients, flat colors only, a limited palette of about eight colors, retro 16-bit look, Aseprite style, all ages, bright cheerful fantasy cavern, not grim, flat side view, orthographic, no perspective distortion. A very wide horizontal composition, about 5 to 1 aspect ratio; if the canvas is taller than that band, paint the band across the middle and fill the area above and below with flat dark continuation #282220, keeping all detail inside the band. This is the FAR BACKGROUND of an underground cavern arena: the camera stands at the arena edge and looks across a deep cave chamber, so the view must read as a distant cavern interior with real depth, NOT as a flat wall close behind the characters. BACKGROUND LAYER ONLY: no ground, no floor, no platform, no characters, no creatures, no props in the near view, no torches, no lanterns, no light sources of any kind, no light shafts, no beams of light, no glow. TOP BAND (the top fifth of the band): completely empty flat solid darkness #282220, no texture, no ceiling, no stalactites, no hanging cones, no spikes, no objects, and nothing touches the top edge. DEPTH LAYERS, from far to near: FAR LAYER: the farthest depth, simple dark silhouettes of distant rock masses and two or three dark side tunnel openings; no continuous floor line, the far depth fades into darkness; these are the darkest and simplest shapes, their edges partly hidden behind the midground, and they never form isolated cutouts against the top band. MIDGROUND: the main readable layer across the middle of the band — several enormous rock masses and broad ledges at different heights that overlap and partly hide each other, irregularly spaced, not a row of evenly spaced pillars; a few tall natural rock pillars rise from behind the ledges; the central part of the frame opens into a deeper recess with one large dark tunnel mouth far behind it; shallow alcoves and recesses, cracks and fissures; this layer carries most of the detail, low in contrast; the rock reads as huge natural cave masses, not a built wall, with only a few faint, short, broken strata hints that fade out, never continuous wavy stripes. NEAR FRAME: at the left and right edges, two dark rock masses frame the view, slightly darker than the midground; no isolated cylinder, column or prop pasted against the top; no hanging shapes. CENTER: the central half of the band stays calm and low in detail so the characters and UI can read. The overlapping ledges, pillars and far silhouettes must create several depth planes, not one flat backdrop. BOTTOM BAND (the bottom third of the band): simple flat dark rock in #282220 fading into shadow, no floor, no ground plane, no continuous horizontal ground line, no stone platform, no pedestal, no baseboard, no props — this area will be covered by a separate ground layer and UI. WHOLE IMAGE: very dark and low in contrast, no bright highlights, no rim lights, no vignette, no complete solid shape that competes for attention; no dense horizontal wavy lines, no repeated banding, no zebra stripes, no wood-grain pattern.
三关变体段（接在共用底座后）：
dungeon：
Use warm limestone for the far and mid rock: dark warm brown-grey, from the darkest #282220 through #3E362C to the lighter #453723; broad calm rock faces and a few wide low ledges; only a couple of faint, broken strata hints, not bands across the wall. GOBLIN LAIR DETAILS, fully built into the rock, only in the midground and far layer, small and low contrast, partly hidden: one broken crude wooden walkway anchored into a distant ledge with its posts set into the rock, its middle hidden behind a rock outcrop; one short pointed stake fence embedded along the edge of a far ledge, partly behind a rock mass; a dark side tunnel mouth with a rough timber frame built into the rock; no isolated fence segments, no floating walkway pieces, no structures sitting on top of ledges like icons; never in the near frame, never at the top, never lit.
underdark：
Use cool desaturated blue-grey rock for the far and mid rock: the rock faces are dark cool blue-grey, not warm brown; the cracks are sharper and more vertical; in the far layer add simple dark silhouettes of a few giant natural rock pillars whose tops fade into the dark top band, slender stone spires rising from distant ledges, thin muted grey web strands between rocks, a few curved spiral tower silhouettes, huge mushroom silhouettes on far ledges, and a distant chasm crossed by a thin stone bridge; add only a few thin, muted blue-violet mineral seams around 256 degrees hue, never saturated purple or magenta; no glowing fungi, no faerie fire, no bricks, no regular masonry.
deep_underdark：
Use very dark neutral grey-black rock for the far and mid rock: the rock faces are grey-black and angular, with broken, step-like ledges; in the far layer add simple dark silhouettes of a city carved into a giant stalagmite, with angular stone halls, buttresses and stepped terraces, a few stone bridges spanning a rift, several mine entrances with dark timber frames, and a row of chimney and vent stacks; a few thin cool silver and copper-grey mineral veins run through the rock as matte metal, not glowing; no forge fire, no glow, no smoke plume, no bricks, no regular masonry.
共用否定后缀（三张共用）：
Do not add any of the following: realistic, photorealistic or 3D rendering; painterly brushwork, smooth anti-aliased lines, gradient or dithered shading, glossy highlights; black or heavy dark outlines; blur or compression artifacts; a vignette, dark corners, or any mood darkening; any saturated purple or magenta anywhere, any color with a hue between 300 and 345 degrees (the underdark's muted 256-degree blue-violet seams are allowed and must stay desaturated); brick patterns, rectangular cut stone blocks, regular masonry joints, mortar lines, tiled surfaces, paved surfaces, a near-view carved or dressed stone wall, a flat wall close behind the characters, a single isolated column or cylinder pasted against the top band, any element touching the top edge, isolated fence segments, floating walkway pieces, structures sitting on top of ledges like icons, a continuous horizontal floor line; dense horizontal wavy lines, repetitive wavy banding, zebra stripes, wood grain, layer-cake stripes, continuous parallel strata across the whole wall; stalactites, stalagmites used as hanging shapes, hanging cones, ceiling spikes, cave curtains; any ground, floor plane, stone platform, pedestal, stage floor, baseboard, path or paving in the lower band; any character, person, creature or animal; any light source of any kind, any torch, brazier, lantern, candle, crystal, glowing object, light shaft, god ray, beam of light, glow, bloom or bright patch; any props in the near view, bones, chains, rubble pile, furniture, murals, paintings, grass, moss, plants, trees, small foreground fungi or glowing fungi (the underdark's far-layer giant mushroom silhouettes are allowed and must stay dark and unlit); bright or saturated colors, any area lighter than the variant's lightest wall color; high contrast edges, rim lights, black outlines; text, letters, numbers, watermark, signature, logo; frame, border, panel, arrow or UI element.
组合方式：每张背景 = 共用底座 + 对应关卡变体段 + 共用否定后缀，拼起来即整段可贴。三张仅岩体形态与色族不同，构图规则一致。
后处理：三张均不去底；最近邻降采样到终稿尺寸，色板量化到 art-bible §4.1 战斗屏场景环境子板（三张共用该子板，新增冷/灰色按 §4.1 两道门入板），单张 ≤32 色；四道机检见 §4。
2.2 连续地面层（scene_stage_ground，三关共用，顶缘以上透明）
画什么：全宽近景地面——干净压实泥土为主，整片平整、中低明度；全幅只保留零星 3–5 颗小石，散点分布、不成排不成堆；顶缘为不规则泥土边＋阴影缝，可带 2–3 颗小石；中央平缓留空；地面跨三关恒定。 不画什么：瓷砖、砖缝、规则铺装、石板块、踢脚线/直亮边；草、木地板；远景/洞壁/天空；角色、生物、道具、火把/灯；中央大石或碎石堆挡站位；满铺碎石、密集砂砾、成排/成堆碎石、亮色浅棕大片、泥点噪声、垃圾杂物。
出图画布：终稿 = 基准屏宽 × ground_h（battle_layout.tres 字段值 100）；本件是极宽薄条，平台无对应宽高比时按横向可平铺纹理条出图（左右无缝，宽度取平台方档，高度取 ground_h 的整数倍），终稿裁/平铺到目标宽高比，禁横向拉伸。试片阶段可按构图比例先出，终稿尺寸读表。
正向提示词：
