 ---
 Perfume Name:
 An original, evocative, and unique name — in French or English.
+
 Tagline:
 A short, poetic sentence — like a perfume advertisement hook.
+
 Poetic Olfactory Description:
 A freeform and expressive description of the scent ambiance evoked by the scene. Use rich sensory, emotional, and metaphorical language. Match the **emotional tone** of the scene: if the mood is calm, sleepy, or melancholic, avoid overly bright or energetic expressions. If the scene is painted or artistic, evoke texture, stillness, or material details rather than action or movement. Be subtle and precise.
 **Important:** Any scents, herbs, or natural elements mentioned here must be consistent with the scene’s setting. Do not invent new locations or scenery that do not appear in the description.
+
 Olfactory Pyramid (technical):
 - Top Notes:
 List 3–4 real, concrete scent materials that would be perceived first. These must be plausible fragrance ingredients (e.g. herbs, resins, citrus peels, spices, aldehydes, etc.). Pick notes that reflect the **real mood, climate, and setting** of the scene. Do not add locations or elements that don’t appear in the scene. If the scene is indoors or includes human presence, include soft, intimate, or textural notes.

 List 3–4 real fragrance elements that give body and soul to the perfume. They must relate directly to the **core emotion, human presence, or material textures** of the scene (e.g. warm fabric, skin, dry flowers, books, wood, canvas). If you mention herbs, flowers, or other elements in the poetic description, include them here.
 - Base Notes:
 List 3–4 real, longer-lasting ingredients such as woods, musks, resins, or earthy accords. These should evoke the **depth, texture, or after-image** of the scene — warmth, silence, stillness, or time passing. Avoid generic bases unless they fit the mood. If the scene suggests furniture, old rooms, or human presence, reflect that with realistic base notes.
+
 Consistency Rule:
 The top, heart, and base notes must not introduce new ideas, plants, or places that were not in the poetic description or the scene. Make sure all notes match elements that appear in either the scene or your poetic text.
+
 General Atmosphere:
 **This section is mandatory.** Provide a short, elegant paragraph summarizing the fragrance’s evolution and overall emotional impression. Keep it artistic, connected to the real details of the scene, and avoid clichés. **Never omit this section.**
+
+Concentration Type:
+**This section is mandatory.**  
+Select the most appropriate perfume concentration for the mood, setting, and intensity of the fragrance. Choose only one of these real categories:
+- **Extrait de Parfum (Parfum)** — the richest, most concentrated version (20–40% essences). Use for intense, luxurious, opulent scenes with deep, long-lasting warmth.
+- **Eau de Parfum (EDP)** — full-bodied but balanced (15–20% essences). Use for sophisticated, versatile scents with a strong presence but wearable daily.
+- **Eau de Toilette (EDT)** — lighter and airy (5–15% essences). Perfect for fresh, casual, daily wear with a brighter, more volatile opening.
+- **Eau de Cologne (Cologne)** — very light, citrusy, and refreshing (2–5% essences). Use for short-lasting, bright, carefree or nostalgic summer moods.
+- **Eau Fraîche** — the lightest splash, mostly water and very low in essence (1–3%). Use for breezy, crisp, natural freshness — coastal, garden, or rain moods.
+- **Body Mist or Brume Parfumée** — extremely soft and delicate, almost like a scented skin veil. Use for cozy indoor scenes, soft linen, skin-close freshness, or when you want a gentle, intimate trail. You may choose the French word “Brume Parfumée” for a poetic touch.
+
+**Important:** The chosen concentration must align with the fragrance’s intensity and story. Do not invent fictional categories or hybrid terms.
+
 Image Description (for marketing visuals):
 Describe an imagined marketing image that captures the perfume’s essence.
 The Image Description must always begin by describing the perfume bottle as the clear, main, and visually dominant subject. The bottle must be obviously recognizable as a perfume bottle — featuring a sprayer or atomizer, an elegant cap, and a refined fragrance label. The label must clearly display the **exact Perfume Name** generated in this output, written exactly as it appears, along with a subtle, elegant mention of the imaginary luxury brand **“FILONI’S.”** The brand name should appear in a smaller, complementary font style, placed above or below the Perfume Name to enhance the overall design without overpowering it.
 Do not use placeholder text like “Perfume Name” — always use the actual fragrance name exactly as you have suggested above.
+
 **Important:** Absolutely never describe or depict any literal characters, humans, body parts, animals, narrative props, weapons, tools, furniture, costumes, or iconic objects from the input scene. Instead, translate any such elements into purely abstract or subtle design cues on the perfume bottle — for example, a hint of color, a texture, a minimal engraving, or an abstract shape. Never describe these objects directly. Never show them literally.
+
 Describe the bottle’s shape, glass texture, cap, and label in fine detail. The glass may have an elegant frosted or matte finish, subtle etching or engraving (such as delicate floral or botanical motifs), or soft decorative elements that evoke refinement and sophistication while remaining tasteful and minimal.
 Do not describe containers that look like liquor bottles, flower vases, or fantasy potion bottles.
 Do not add narrative illustrations, characters, or storytelling scenes on the bottle — only subtle, abstract decorative details that highlight a luxury perfume aesthetic.

 – No invented scenery or extra context is added.
 – The poetic description and pyramid share the same notes and details.
 – The **General Atmosphere** section is always included and consistent with the rest.
+– The **Concentration Type** is always present and plausible for the scene.
 – The Image Description must mention the exact Perfume Name on the label and focus exclusively on the perfume bottle as the main subject.
 – Never mention or show humans, faces, body parts, characters, animals, or narrative props literally.
 – Any props, costumes, or iconic objects must be abstracted into subtle decorative or textural cues only.
