Phase 1: Concept Exploration

1.1 Generate 25 SVG Concepts

Create 25 SVGs organized as 5 concepts x 5 variations:

Naming: logo-{concept}-{variation}-{description}.svg

• Example: logo-01-a-witch-smile.svg through logo-01-e-witch-drink.svg

5 Concepts = 5 meaningfully different character/design interpretations 5 Variations per concept = different poses, expressions, props, or detail levels

SVG Requirements:

• ViewBox: 0 0 200 200 (square for framed logos)
• All paths must be clean, optimized vectors
• Self-contained — no external fonts, no raster images
• Include background rect for preview (production versions will strip it)
• Apply the user's chosen palette, frame, and style consistently

Diversity rules across the 5 concepts:

• Concept 1-2: Closest to user's brief (safe/expected)
• Concept 3: Stylistic twist (different rendering approach)
• Concept 4: Simplified/minimal version
• Concept 5: Bold/experimental direction

Variation rules across 5 per concept:

• Variation A: Default pose/state
• Variation B: Action pose (holding prop, gesturing)
• Variation C: Different expression (happy, wink, serious)
• Variation D: With accessory/prop variation
• Variation E: Simplified icon version (works at 32px)

1.2 Build Grid Gallery Preview

Create preview-gallery.html — dark background grid showing all 25 concepts.

Read references/gallery-grid-template.md for the HTML template.

Gallery requirements:

• Dark background (default) matching Reka Grafix showcase style
• 5 columns x 5 rows grid layout
• Each cell shows the SVG centered on dark card
• Row headers showing concept name
• Column headers showing variation type (A-E)
• Click to select → highlights with brand color border
• Dark/light mode toggle
• Concept grouping — visually separate the 5 concept rows

1.3 Build Individual Showcase Pages

Create showcase.html — individual logo showcase on branded color background.

Read references/individual-showcase-template.md for the HTML template.

Showcase requirements:

• Full-screen branded background color (e.g. #3045C9 blue like Reka Grafix)
• Logo centered, white on brand color
• Navigation arrows (prev/next) to browse all 25
• Logo name and concept info below
• Download SVG button per logo
• Dark/light background toggle

1.4 Present Phase 1 Output

Tell the user:

• "Open preview-gallery.html to see all 25 concepts in a grid"
• "Open showcase.html to browse each logo individually on branded background"
• "Tell me which concept row (1-5) you like, or mix elements: e.g. 'concept 2 pose with concept 4 style'"

---

Phase 2: Selection & Refinement

2.1 Gather Feedback

User picks a concept direction. Clarify:

• Which concept row?
• Preferred variation(s)?
• Any changes to pose, expression, detail?
• Keep same palette/frame/style or adjust?

2.2 Generate 6 Refined Variations

Based on selected concept, create 6 polished variations:

File	Description
final-01-{name}.svg	Primary — the hero version
final-02-{name}.svg	Action variation
final-03-{name}.svg	Expression variation
final-04-{name}.svg	With prop/accessory
final-05-{name}.svg	Simplified (works at 32px)
final-06-{name}.svg	Wordmark combination (logo + brand name)

2.3 Build Refinement Preview

Update preview-gallery.html to show the 6 refined versions with:

• Large preview (centered, prominent)
• Size tests: 200px, 100px, 64px, 32px, 16px
• Dark background and light background comparison
• Side-by-side before/after if applicable

2.4 Present Phase 2 Output

Ask: "Which version is the winner? Any final tweaks before I prepare production files?"

Phase 3: Production Export

3.1 Create Production SVG Set

From the chosen final logo, generate:

File	Spec
production/logo-dark.svg	For dark backgrounds, NO bg rect
production/logo-light.svg	For light backgrounds, NO bg rect
production/logo-icon-dark.svg	Icon only, 200x200 viewBox, NO bg rect
production/logo-icon-light.svg	Icon only, 200x200 viewBox, NO bg rect
production/logo-wordmark-dark.svg	With brand name, for dark bg
production/logo-wordmark-light.svg	With brand name, for light bg

Production rules:

• NO background <rect> — these embed into pages that provide their own bg
• Unique gradient IDs per file (avoid conflicts on same page)
• Optimized paths (remove unnecessary decimals, merge compatible paths)
• Self-contained (no external dependencies)

3.2 Build Final Preview Page

Create logo-preview.html with real-world mockup sections:

1. Grid showcase — all 6 finals on dark background (Reka Grafix grid style)
2. Individual showcase — hero logo on branded color background
3. Size test — 200px, 100px, 64px, 32px, 16px on dark and light
4. Navigation mockup — dark and light nav bar with logo
5. Social media avatar — circular crop at profile picture sizes
6. Brand color palette — swatches with hex codes

3.3 Export Assets Summary

Present a table of all generated files:

production/
  logo-dark.svg
  logo-light.svg
  logo-icon-dark.svg
  logo-icon-light.svg
  logo-wordmark-dark.svg
  logo-wordmark-light.svg
preview-gallery.html
showcase.html
logo-preview.html

SVG Design Principles

Monochrome Technique (Reka Grafix Reference)

The monochrome style from the reference images uses these specific techniques:

1. Single fill color on transparent/colored background
2. Circle container with consistent stroke width
3. Character fills background — subject occupies 70-80% of circle area
4. Negative space for detail — eyes, mouth, clothing defined by background showing through
5. No outlines on monochrome negative-space — shapes are carved, not drawn
6. Line-art alternative — same character with visible stroke outlines instead
7. Consistent weight — stroke widths scale proportionally

SVG Optimization

• Use <path> with optimized d attributes — minimize control points
• Prefer <circle>, <rect>, <ellipse> over path equivalents where possible
• Group related elements with <g> for logical structure
• Set fill-rule="evenodd" for negative space designs
• ViewBox always 0 0 200 200 for icon marks
• ViewBox 0 0 400 200 for wordmark combinations

Scalability Rules

Size	Requirement
200px+	Full detail version
64-100px	Reduce fine details, thicken strokes
32-48px	Simplified version, remove small elements
16px	Silhouette/minimal — must still be recognizable

---

Efficiency Rules

1. Bulk operations — use sed for color changes across multiple SVGs
2. Template-driven — use reference HTML templates, don't write from scratch
3. Confirm before generating — validate brief before producing 25 SVGs
4. Smart grouping — 5x5 grid is more useful than 25 random concepts
5. Preview-first — always provide HTML preview, don't just list SVG files
