@@ -37,7 +37,7 @@ The game art direction is adult-oriented multi-world pinup:
 - Use the manager-preferred clean card style established by the C0007 baseline approach: large silhouette first, crisp costume/equipment detail, clean focal areas, broad elemental or gravity shapes, and backgrounds that support the character instead of competing with her.
 - Keep visual noise extremely controlled. Do not fill images with tiny sparkles, glitter dust, particle clouds, micro-shards, confetti debris, random luminous specks, hairline glowing filigree, spiderweb crack networks, or glittering wire/vine nets. Show damage through large readable cut-open panels, bent armor plates, broken equipment pieces, broad impact arcs, and a few bold elemental shapes, with negative space around the face, torso, weapon, and main silhouette so the card reads cleanly at game size. High-damage art dominated by thin marks or decorative shredding fails even if it looks detailed.
 - Adult damage presentation is a core reward and should be aggressively favored, not treated as something to minimize. From `damage-2` onward, large opened clothing/gear panels should clearly reveal non-sensitive areas such as shoulders, side torso, abdomen, hips, upper thighs, back, and mature upper-body silhouette whenever the outfit allows it. `damage-3` and `damage-4` should be composed as adult-only damaged-costume pinup art: only battered opaque remnants, torn straps, broken armor fragments, damaged support pieces, hair, pose, or equipment should preserve required coverage. A high-damage card that looks modest, teen-safe, fully re-covered, or protected by clean replacement underlayers fails even if it has scratches or debris.
-- High-damage stages should choose poses and camera angles that reveal the damage instead of hiding it: side-back, rear three-quarter, twisted torso, hip-forward stance, exposed-leg kneeling, sitting defeat, torn-cloak back view, or arched wounded posture. A straight front pose that lets intact fabric, a skirt, or a bodysuit hide most of the adult body exposure fails for `damage-3` and `damage-4`.
+- High-damage stages should choose poses and camera angles that reveal the damage instead of hiding it: side-back, rear three-quarter, twisted torso, hip-forward stance, exposed-leg kneeling, sitting defeat, torn-cloak back view, or arched wounded posture. Use both low-angle and high-angle framing, and rotate poses across front/side/rear variants so repeated straight-on framing does not dominate. A straight front pose that lets intact fabric, a skirt, or a bodysuit hide most of the adult body exposure fails for `damage-3` and `damage-4`.
 - Do not solve coverage by adding a new safe outfit. Clean replacement underlayers, pristine wraps, censorship effects, strategically convenient hair curtains, or unbroken new coverage panels are not acceptable high-damage coverage. Coverage must look like damaged remnants of the original costume, damaged armor fragments, or battle-worn support pieces.
 - Damage should be distributed across the whole outfit and armor system, but not as identical small tears everywhere. High-damage and defeated cards should show damage on headgear or hair accessories, shoulders, chest armor or bodice, back or cloak, sleeves, gloves, abdomen, waist, hips, thighs, knees, boots, and weapon accessories as appropriate, with each zone affected by the same readable impact direction or material-specific failure. Group destruction around a few clear impact paths rather than peppering every zone with tiny cuts. Do not leave a major region pristine while only one area is destroyed; keep opaque remnants over intimate areas so the image stays combat-damage focused.
 - Do not selectively protect torso or rear-body gear. Bust armor, bodice panels, torso straps, side armor edges, hip plates, rear waist plates, rear skirt or coat panels, and seat armor should show the same level of dents, tears, broken straps, missing trim, and deformation as the rest of the outfit. These areas should read as damaged equipment/clothing, not explicit display, and opaque remnants must still preserve required coverage.
