Changelog

Audited all 10 scenarios and game inputs for correctness:

• Measuring cups can now be used more than once — tap to add, red button to remove
• Number line and fraction bar scale to the actual answer range (was capped at 3)
• “Get as close as you can” note for cups — some answers can't be made exactly
• Fraction bar shows ticks above 1 (e.g. 1¼, 1½)

After running a Hypandra Reggio pedagogy review and AI principles audit, three repairs:

• AI coaching labeled as AI-generated (“AI Coach says:” + sparkle icon) with student reaction buttons (Helpful / Not sure / Confusing)
• “What part is tricky?” prompt before delivering hints — students select what they're stuck on so hints are more targeted
• Thinking Journal page (/journal) — surfaces student reasoning across sessions, linked from the completion screen

• Teachers get their own prompt overrides — edits only affect their students
• “Overridden” badge and “Reset to default” on the dashboard
• Required-variable validation confirms coaching prompts still work after edits

• Hypandra curiosity badge embedded site-wide
• Site footer with links to about and changelog

• Renamed from “Fraction Kitchen” to “Curious Fractions”
• Custom domain: curiousfractions.com
• OpenGraph and Twitter metadata added

Core game built in one session:

• Estimate → Reveal → Reflect game loop with three input modes (measuring cups, number line, fraction bar)
• 10 recipe scenarios across easy/medium/hard difficulty
• Progressive hints (scaling diagrams, zone hints, benchmark references, AI text)
• AI coaching via OpenRouter with database-stored prompt templates
• Teacher dashboard with prompt editor and scenario browser

• Scaffolded from cb-oss-template
• BetterAuth with email/password, Supabase PostgreSQL, migration guard
