Adds Tesseract-based OCR pre-processing that computes pixel-level text
positions, margins, spacing, and alignment before LLM analysis. This
enables detection of subtle layout differences that vision models miss
(e.g. 2.8% vs 6.4% headline margin, 83px vs 39px date gap).
OCR measurements injected into 10 checks across all client profiles:
- Amazon: margins, typography, headline_layout
- Static General: element_alignment, safety_area, visual_hierarchy_general,
text_readability_general, text_edge_clearance
- L'Oreal: text_readability
- Diageo/Unilever KV: visual_hierarchy
Non-blocking: if Tesseract is unavailable, checks run with visual
estimation only. Production requires: sudo apt install tesseract-ocr

Created 4 new "_general" QC check modules optimized for digital static assets:
- visual_hierarchy_general: Digital hierarchy assessment (removed POS/physical viewing distances)
- product_visibility_general: Digital product presentation (removed POS terminology)
- logo_visibility_general: Digital logo prominence (removed 3m/1m viewing distance requirements)
- call_to_action_general: Digital CTA effectiveness (added clickability and mobile considerations)
Updated Static General profile (static_general.json):
- Now includes 10 AI vision-focused checks
- Even weighting: 1.0 per check for 100-point scale
- Total weight: 10.0 for proper scoring calculation
- All checks assigned to Gemini LLM
- Updated description to clarify focus on AI vision capabilities
Profile focuses exclusively on checks that only AI vision models can perform,
excluding physical file properties that Twist system handles (file size, format,
resolution, naming, aspect ratio, bleed, crop marks, etc.).
