Enhance Cognitive Signal Engine™ — PDF executive upgrade, media cost impact, UI improvements

[anilp-stack]

Summary

• Executive Decision Block (PDF Page 2): Single CMO-facing card combining CPCi, memory score, media cost multiplier, and cold audience deployment risk into one unmissable decision: DO NOT SCALE / OPTIMISE BEFORE SCALING / READY TO SCALE
• Media Efficiency Impact (PDF Page 2): Dynamic multiplier line — This creative will cost ~X× more media to achieve the same recall — with waste callout if multiplier > 1.5
• Visual signal bars (PDF Page 4): Horizontal progress bars for Attention, Memory, Emotional Valence, and Cognitive Load for instant scan-ability
• Cover page enhancements: Client name in 22px bold, CPCi interpretation line (tier-adaptive, centred below the score)
• Cold Audience Deployment Risk badge (Strategic page): HIGH / MODERATE / LOW, colour-coded, driven by memory score
• Reduced PDF redundancy: Removed duplicate CPCi explanation and "What This Means" from Page 3; Page 3 now shows formula detail not covered elsewhere
• Why This Matters block (app UI): Media cost multiplier line (18px, colour-coded) + waste callout when multiplier > 1.5
• CTA block: "Ready to test your creatives before media spend?" with primary Analyze button and PDF download at bottom of results
• Science tab: TRIBE v2 → CPCi architecture diagram (Layer 1 / Layer 2)
• Bug fixes: HTML rendering fix for CTA block; client name flowing correctly through all PDF download paths; venv path fix in launch.json

Test plan

• Upload a creative and verify CPCi, memory, and multiplier values are consistent across the app UI and all PDF pages
• Generate PDF with a client name — confirm it appears on cover page in large bold text
• Test all three Executive Decision tiers: CPCi < 40, 40–70, > 70
• Verify Cold Audience Deployment Risk badge appears on Strategic page with correct colour
• Confirm signal bars render on Page 4 without layout overflow
• Click "Analyze Your Creative" CTA — confirm cached results clear and uploader is shown
• Confirm no raw HTML is visible in the app UI
