Add Spring Festival workflows: spring_text_image, spring_text_image_EN, and spring_3d
spring_text_image – Chinese prompt version of a multi-agent content pipeline (planner → copywriter → editor → poster generation).

spring_text_image_EN – English prompt version of the same workflow structure, adapted for broader international usage.

spring_3d – A simplified 3D scene generation workflow that outputs Blender Python scripts for Spring Festival themed scenes.

+
+          # Goal
+          Convert the user's one-sentence idea into a detailed, quantified **3D Design Spec** executable by Blender Python (bpy).
+
+          # HARD COMPLEXITY REQUIREMENTS (must satisfy)
+          - Scene must include at least **12 distinct object types** (not counting duplicates).
+          - Total object count (including duplicates/instances) must be **>= 40**.
+          - Must include: ground/terrain, main structure(s), props, decorations, food/tableware, lighting fixtures, and background elements.
+          - Must specify at least **6 materials** with procedural node hints (no flat colors).
+          - Must specify lighting with **3-point lighting** (key/fill/rim) or a justified alternative.
+          - Must include camera composition target (rule of thirds / centered symmetry / isometric).

+          # Output Format (STRICT Markdown)
+          ## 1. Scene Overview
+          * **Theme**:
+          * **Style**: (Low Poly / Voxel / Semi-realistic / Realistic)
+          * **Scale**: (e.g., 30m x 30m)
+          * **Mood**:
+          * **Composition**: (how camera frames the scene)
+          * **Object Complexity Target**: (>=12 types, >=40 total)
+
+          ## 2. Object List (Quantified)
+          For EACH object type:
+          * **Name**:
+          * **Quantity**:
+          * **Dimensions**: (L x W x H meters)
+          * **Geometry**: (primitive composition)
+          * **Material Look**: (procedural node idea, at least 2-color variation)
+          * **Placement**: (coordinate range and logic)
+
+          ## 3. Lighting & Camera
+          * **Key Light**:
+          * **Fill Light**:
+          * **Rim Light**:
+          * **Optional Practical Lights**: (lantern glow, etc.)
+          * **Camera**: (lens, position, target)
+
+          # Constraints
+          - Do NOT ask user for more info; improvise missing details.
+          - Keep geometry code-friendly and physically plausible.

+          Produce a step-by-step plan that guarantees the Architect can generate a rich scene.
+
+          # HARD REQUIREMENTS
+          - Plan must contain **>= 12 build steps**, each step builds one object type (and applies its material).
+          - Each step must include: dimensions, count, coordinate ranges, and material recipe name.
+          - Include at least **2 scatter steps** (decorations/props).
+          - Include a final step that sets camera, lighting, render settings, and a "scene summary print".

+          No extra text outside code.
+
+          # QUALITY BAR (must satisfy)
+          - Create **>= 12 distinct object types** and **>= 40 total objects** (instances allowed).
+          - Must create a **Ground/Terrain** and **background elements** (e.g., walls, fence, trees, skyline, distant lights).
+          - Must build a **main structure** (gate/door/frame) with layered parts.
+          - Must include a **table + 6+ tableware items** and **>= 20 dumplings** with scatter.
+          - Must include **decorations**: couplets, lanterns, knots, banners, string lights, fireworks props, etc.
+          - Must set up **Key/Fill/Rim** lights + optional emissive lantern material.
+          - Must set camera with a target empty and use a Track To constraint.
+
+          # ENGINEERING RULES
+          - Prefer bpy.data mesh creation + modifiers; avoid edit-mode toggling.
+          - Avoid context-fragile ops when possible; if using bpy.ops, do it consistently in Object Mode.
+          - Use Collections: Environment, Structure, Props, LightsCam.
+          - Use naming: ENV_, STR_, PROP_, LGT_, CAM_.
+
+          # MATERIAL RULES (MANDATORY)
+          - NO flat Base Color. Use Noise Texture + ColorRamp to mix at least 2 colors.
+          - Create a small material library:
+            - make_noise_material(name, color_a, color_b, roughness_range)
+            - make_emissive_material(name, color, strength)
+          - Assign materials to ALL meshes.
+
+          # REQUIRED SCRIPT STRUCTURE
+          1) imports + seed
+          2) reset_scene() (delete objects, purge orphans safely)
+          3) collection setup
+          4) material library functions
+          5) geometry helper functions (add_cube, add_cylinder, add_sphere, add_plane)
+          6) build scene following the Plan
+          7) lights + camera + render settings
+          8) final summary prints (object counts by collection)
+
+          Output: ONE python code block only.
