[USER INPUT — REQUIRED AT TOP]
SIGNATURE_NAME: ภาคิน
LEGIBILITY_LEVEL: Very Low
ABSTRACTION_LEVEL: High
LETTER_MERGE_INTENSITY: Strong
SIGNATURE_SPEED: Fast
UNDERLINE_PROBABILITY: Medium
INK_COLOR: Obsidian Black
BACKGROUND_COLOR: White paper

[CONTROL OVERRIDES]
- SIGNATURE_NAME is the only identity source for all signatures in the sheet.
- The output must be a 3x3 nine-grid of signature variations for the same person.
- The signatures must look like real personal autograph explorations, not readable handwriting samples.
- Literal readability must be suppressed aggressively.
- The result must feel premium, practiced, elegant, and naturally hand-signed.

LEGIBILITY CONTROL
- If LEGIBILITY_LEVEL is Very Low:
  - the signatures must not be instantly readable
  - do not render the name as a clearly readable word
  - the viewer should perceive signature gesture first, readable text second
  - compress the name structure until it becomes autograph-like rather than normally written

- If LEGIBILITY_LEVEL is Low:
  - keep the signatures difficult to read, but allow slight hints of the underlying name
  - avoid clear full-word readability

- If LEGIBILITY_LEVEL is Medium:
  - allow partial readability, but still prioritize signature behavior over handwriting clarity

ABSTRACTION CONTROL
- If ABSTRACTION_LEVEL is High:
  - aggressively stylize the internal structure of the name
  - allow loops, collapsed forms, overlaps, symbolic compression, elongated exits, and partial abstraction
  - preserve identity cues only indirectly

- If ABSTRACTION_LEVEL is Medium:
  - keep the form signature-like, with moderate distortion and selective readability

- If ABSTRACTION_LEVEL is Low:
  - keep more of the name structure recognizable, but still as a true signature

LETTER MERGE CONTROL
- If LETTER_MERGE_INTENSITY is Strong:
  - major letter groups must connect heavily
  - avoid visible separation between characters
  - merge strokes until the name feels like one continuous identity mark
  - syllable boundaries must not remain obvious

- If LETTER_MERGE_INTENSITY is Medium:
  - merge characters naturally with occasional visible internal structure

- If LETTER_MERGE_INTENSITY is Light:
  - allow a looser signature with some character hints still visible

SPEED CONTROL
- If SIGNATURE_SPEED is Fast:
  - the signatures must feel rapidly executed, practiced, and natural
  - use swift stroke motion, compressed rhythm, and confident exits
  - avoid careful construction and slow penmanship

- If SIGNATURE_SPEED is Medium:
  - allow a balanced signing rhythm with elegance and control

- If SIGNATURE_SPEED is Slow:
  - keep it signature-like, but slightly more deliberate and poised

UNDERLINE CONTROL
- If UNDERLINE_PROBABILITY is High:
  - several variations may include underlines, finishing slashes, or base sweeps
  - do not apply them identically across all 9

- If UNDERLINE_PROBABILITY is Medium:
  - a few variations may include subtle underline behavior or final slash motions

- If UNDERLINE_PROBABILITY is Low:
  - only occasional underline or finishing stroke may appear

[PROMPT]
Create a premium signature exploration sheet showing 9 different handwritten signature variations derived from SIGNATURE_NAME.

PRIMARY OBJECTIVE
- The output must be exactly nine signature concepts arranged in a clean 3x3 grid.
- All 9 signatures must be based on the same SIGNATURE_NAME only.
- The page must feel like a professional signature concept board for one person.
- The signatures must look difficult to read, highly stylized, and authentically hand-signed.
- The final result must not resemble a typography sheet, text rendering sheet, handwriting worksheet, or name-writing practice page.

CRITICAL MASTER RULE
- Do NOT write SIGNATURE_NAME as normal readable text.
- Do NOT render it character by character.
- Do NOT preserve clean literal syllables or clear textbook Thai letter construction.
- Treat SIGNATURE_NAME as an identity source, not as display text.
- The final result must look like signature marks derived from the name, not the plain written name itself.

GRID LAYOUT RULES
- Arrange the signatures in a balanced 3x3 nine-grid composition.
- One signature per position only.
- Keep generous spacing between signatures.
- The sheet must feel minimal, clean, and premium.
- Use a plain BACKGROUND_COLOR background.
- A very subtle paper texture is allowed, but only if minimal and realistic.
- No boxes, no labels, no captions, no numbering, no decorative dividers, no mockup context.

SIGNATURE IDENTITY LOGIC
- Every signature must come from the same underlying Thai name: SIGNATURE_NAME.
- Do not invent a different name.
- Do not convert the name into English.
- Do not reduce it to a generic Latin-style cursive look.
- Preserve Thai-name signature energy and identity cues, but stylize them heavily into a personal autograph form.
- The signatures may hint at the original name, but must not present it as clearly readable writing.

ANTI-READABILITY LOGIC (CRITICAL)
- Literal readability must be actively reduced.
- Avoid evenly spaced letter groups.
- Avoid clearly formed full syllables.
- Avoid neat word spacing.
- Avoid textbook Thai handwriting.
- Avoid the appearance of “someone carefully writing their name so others can read it.”
- The first impression must be “signature,” not “written word.”
- If any signature becomes too readable, compress it further, merge more internal strokes, reduce visible character clarity, and prioritize overall gesture silhouette.

SIGNATURE ABSTRACTION RULES
- Letters must connect, overlap, merge, compress, collapse, simplify, and flow together.
- Individual characters must not remain cleanly separated.
- Allow partial loops, compressed stems, rapid joins, tapered endings, sweep lines, and signature-like symbolic compression.
- Some internal parts may become nearly abstract as long as the result still feels derived from the same identity.
- At least 7 out of 9 signatures must be hard to read immediately.
- At least 3 out of 9 signatures must be highly illegible, premium, elegant, and autograph-like.
- None of the 9 should resemble normal neat handwriting.

STYLE VARIATION LOGIC
Generate 9 clearly different signature behaviors for the same name. Variation must come from gesture, rhythm, compression, slant, line economy, abstraction, underlines, loops, finishing strokes, and overall signature silhouette.

The nine variations should feel like distinct directions such as:
1. compressed luxury signature
2. fast angular autograph
3. looped abstract signature
4. slash-driven executive signature
5. narrow vertical signature
6. wide sweeping signature
7. underlined illegible autograph
8. monoline compressed signature
9. couture-style abstract signature

IMPORTANT
- These are internal directions only.
- Do not display any style labels in the image.
- Do not add graphics to make them different.
- Difference must come from true signature behavior only.

HAND MOTION & FLOW RULES
- Every signature must feel like it was produced by a real human hand.
- Simulate authentic signing rhythm, practiced motion memory, natural speed, acceleration, pressure release, and continuous gesture flow.
- Favor one continuous motion or a few tightly connected motions.
- Avoid slow construction.
- Avoid traced appearance.
- Avoid hesitant, shaky, or overly corrected lines.
- The signatures must feel confident and repeatable, as if a real person has signed this way many times.

LINE QUALITY & INK RULES
- Use INK_COLOR only.
- Simulate a refined premium pen line with crisp but organic edges.
- Show subtle pressure variation, tapered starts, tapered exits, and believable handwritten energy.
- Slight natural inconsistency is welcome if it feels realistic.
- Keep the line elegant, thin-to-medium, and premium.
- No thick marker style.
- No brush lettering.
- No pencil texture.
- No calligraphy poster style.

VISUAL PRESENTATION RULES
- Minimal white-paper presentation only.
- Show only the nine signatures.
- No hand, no pen, no desk, no notebook, no certificate, no branding, no UI, no watermark.
- No decorative flourishes unless they emerge naturally from the signature itself.
- Keep the comparison sheet clean and uncluttered.

SUCCESS CONDITION
- A viewer should say: “These look like real personal signature options.”
- A viewer should NOT say: “This is just the same name written nine times.”
- The final result must feel premium, elegant, practiced, and difficult to read.
- The grid must function as a real signature exploration board for one Thai name.
