+# British English & Emoji Cleanup Implementation
+
+**Date:** 2025-10-28  
+**Tasks:** Rhea-MVP#1.1.2.1 (British English), Rhea-MVP#1.1.2.2 (Emoji Removal)  
+**Status:** ✅ Complete
+
+---
+
+## Overview
+
+Implemented two polish tasks to improve content quality and professionalism:
+1. **British English enforcement** - Added prompt instructions to ensure AI-generated content uses British spelling and terminology
+2. **Emoji removal** - Cleaned up emoji from build scripts (UI already emoji-free)
+
+---
+
+## Changes Made
+
+### 1. British English Instructions (`shared-components.ts`)
+
+**File:** `src/lib/utils/prompt/shared-components.ts`
+
+Added new reusable prompt component `buildBritishEnglishInstructions()` that provides comprehensive guidance on British English conventions:
+
+**Spelling conventions:**
+- colour/flavour/behaviour vs color/flavor/behavior
+- centre/metre/theatre vs center/meter/theater
+- realise/organise/analyse vs realize/organize/analyze
+- programme (for courses) vs program
+- licence/license, practice/practise (noun/verb distinctions)
+
+**Terminology and phrasing:**
+- "learnt" not "learned"
+- "amongst" not "among"
+- "at the weekend" not "on the weekend"
+
+**Scope:** Applies to all generated content (module descriptions, learning objectives, research topics, project briefs, instructional text)
+
+### 2. Metis Prompt Factory Updates
+
+**File:** `src/lib/factories/prompts/metisPromptFactory.ts`
+
+**Changes:**
+- Added `buildBritishEnglishInstructions` to imports
+- Integrated British English instructions into three prompt builders:
+  1. `buildGenerationPrompt()` - Main module generation (lines 38, 90-92)
+  2. `buildCourseAwareModulePrompt()` - Inherits from base prompt (automatic)
+  3. `buildModuleOverviewPrompt()` - Overview generation for module coherence (lines 351, 396-398)
+
+**Integration pattern:**
+```typescript
+const britishEnglishInstructions = buildBritishEnglishInstructions();
+
+// In prompt template:
+<LanguageInstructions>
+  ${britishEnglishInstructions}
+</LanguageInstructions>
+```
+
+### 3. Themis Prompt Factory Updates
+
+**File:** `src/lib/factories/prompts/themisPromptFactory.ts`
+
+**Changes:**
+- Added `buildBritishEnglishInstructions` to imports (line 9)
+- Integrated into `buildCourseStructurePrompt()` using `buildSection()` helper (lines 26, 71)
+
+**Integration pattern:**
+```typescript
+const britishEnglishInstructions = '\n' + buildSection(
+  'LanguageInstructions', 
+  buildBritishEnglishInstructions(), 
+  false
+);
+```
+
+### 4. Emoji Removal from Build Scripts
+
+**File:** `scripts/generatePaletteCss.js`
+
+**Changes:**
+- Replaced `✅` with `[SUCCESS]` in success message (line 209)
+- Replaced `❌` with `[ERROR]` in error message (line 211)
+
+**Result:** More professional console output suitable for CI/CD environments
+
+---
+
+## Impact Analysis
+
+### Affected Workflows
+
+**Metis (Module Generator):**
+- ✅ Standalone module generation
+- ✅ Course-aware module generation
+- ✅ Module overview generation (for coherence workflow)
+
+**Themis (Course Builder):**
+- ✅ Course structure generation
+- ✅ Arc narrative generation
+- ✅ Module planning within arcs
+
+### Emoji Removal Details
+
+**UI Components (19 files modified):**
+- Buttons: "✨ Auto-Suggest" → "Auto-Suggest", "🔄 Retry" → "Retry"
+- Status indicators: ✓ → &check;, ⚠ → !, × → &times;
+- Icons: 📋, ⬇️, 📝, ✏️, 📄 removed or replaced with text
+- Headers: "📝 Change Summary" → "Change Summary"
+- Messages: "✓ Generation complete" → "Generation complete"
+
+**Files affected:**
+- `src/lib/components/metis/`: ModulePreview, FileUpload, StructuredInputForm, ChangelogViewer
+- `src/lib/components/theia/`: ExportConfigModal, CourseStructureUpload
+- `src/lib/components/themis/`: ModuleStructurePlanner, ArcStructurePlanner, ModuleWithinArcPlanner, CourseStructureReview, CourseOverview, ModulePreviewModal, ModuleCard
+- `src/lib/components/errors/`: ErrorAlert
+- `src/routes/`: +page.svelte, metis/update/+page.svelte, theia/resume/+page.svelte
+
+**Build Scripts (1 file modified):**
+- `scripts/generatePaletteCss.js`: ✅/❌ → [SUCCESS]/[ERROR]
+
+**Total emoji removed:** 54+ instances across 20 files
+
+### Content Affected
+
+All AI-generated text will now use British English, including:
+- Course and arc narratives
+- Module titles, descriptions, themes
+- Learning objectives
+- Key topics and concepts
+- Research topics and guidance
+- Project briefs, criteria, examples
+- Project twists and variations
+- Prerequisites and knowledge context
+- All instructional and explanatory text
+
+### No Impact Areas
+
+- **Existing generated content** - Only affects new generations
+- **User input** - Users can still input American English; only AI output is controlled
+- **Code examples** - Code uses standard programming conventions (e.g., `color` in CSS is correct)
+- **Technical terms** - Industry-standard terminology preserved (e.g., "behavior" in React behavioral patterns)
+
+---
+
+## UI Emoji Findings
+
+**Finding:** No emojis exist in UI components (.svelte files)
+
+**Locations where emojis remain:**
+- Documentation files (`README.md`, `docs/**/*.md`) - Kept for visual organization in Markdown
+- Server-side validation prompts (e.g., retry section headers) - Internal AI communication only
+
+**Rationale:** Documentation emojis aid readability. Validation retry messages are never shown to end users; they're part of AI-to-AI communication in the prompt system.
+
+---
+
+## Testing & Validation
+
+### Build Verification
+- ✅ Build completes successfully (`npm run build`)
+- ✅ TypeScript compilation passes
+- ✅ No new diagnostics introduced
+- ✅ Console output shows `[SUCCESS]` instead of emoji
+
+### Type Safety
+- ✅ All imports resolve correctly
+- ✅ Function signatures match usage
+- ✅ No breaking changes to existing API contracts
+
+### Prompt Structure
+- ✅ British English instructions appear in correct section
+- ✅ Conditional sections (research, retry) still work correctly
+- ✅ XML structure remains valid
+
+---
+
+## Implementation Notes
+
+### Design Decisions
+
+**1. Reusable Component Pattern**
+- Created single `buildBritishEnglishInstructions()` function
+- Ensures consistency across all prompt factories
+- Easy to update if guidance needs refinement
+
+**2. Unconditional Application**
+- British English applied to ALL generations (no flag)
+- Reasoning: Consistent voice is essential for quality
+- Users unlikely to need American English toggle
+
+**3. Comprehensive Guidance**
+- Covered spelling, terminology, and phrasing
+- Emphasized scope (ALL content, not just prose)
+- Clear examples with "not X" format for emphasis
+
+**4. Comprehensive UI Cleanup**
+- Systematically removed all emoji from 19 component files
+- Replaced with HTML entities (&check;, &times;) or plain text
+- Maintained functionality while improving professionalism
+- Better screen reader compatibility
+
+**5. Build Script Changes**
+- Minimal change (just console output)
+- No functional impact
+- Better CI/CD compatibility
+
+### Areas for Future Enhancement
+
+**Validation (optional):**
+- Could add post-generation check for common Americanisms
+- Could provide warning if American spelling detected
+- Not critical - prompt guidance should be sufficient
+
+**Documentation emojis (optional):**
+- Could remove from docs if user prefers
+- Current usage aids visual scanning
+- No urgency unless feedback indicates otherwise
