Created config-panel/ subdirectory and extracted reusable UI components
from the monolithic 2550-line ConfigPanel.tsx file.
Extracted components:
- utils.tsx: getScaffoldingSummary() function
- SubOption.tsx: Nested toggle UI component
- ToggleOption.tsx: Main toggle option with description
Changes:
- Created src/app/create/worksheets/addition/components/config-panel/ directory
- Moved 3 helper functions/components to separate files (~240 lines)
- Updated ConfigPanel.tsx to import from new locations
- Removed unused imports (Checkbox, findNearestPreset)
- File size reduced: 2550 → 2306 lines (-244 lines)
Zero functionality change - all components work identically.
Part 1 of 5-phase refactoring plan.

Add comprehensive blog post examining why the soroban never reached US schools:
- Historical context: abacus in 19th century American classrooms vs Japan's institutionalization
- Honest assessment: no meaningful "revival" is happening (2,000 students out of 35M is not a revival)
- What we're missing: number sense, mental math fluency, cognitive benefits
- Structural barriers: curriculum inertia, no teacher training, calculator culture
- What it would actually take: 20-25 years, billions of dollars, systemic restructuring
- Actionable alternatives: tools like Abaci.one for individuals who can't wait for schools
Key themes:
- Evidence-based and honest about the bleak current state
- Pedagogically grounded in learning science
- Accessible solutions (free open-source tools vs $200/month programs)
- Direct: "We chose calculators. They chose soroban. The results speak for themselves."

Fixes production error "Cannot read properties of undefined (reading 'carryBoxes')"
that occurred when users tried to adjust difficulty settings.
Root cause: displayRules was undefined for new users or users with old V1 config
in database. Difficulty adjustment buttons accessed displayRules.carryBoxes without
checking if displayRules existed first.
Changes:
- AdditionWorksheetClient: Initialize displayRules with defaults when missing
- ConfigPanel: Use null-coalescing operators instead of non-null assertions
- ConfigPanel: Add error logging when required fields are missing
- NEW: WorksheetErrorBoundary component to catch all errors in worksheet page
- page.tsx: Wrap client component with error boundary
This ensures users see helpful error messages instead of blank pages,
and never need to open the browser console to understand what went wrong.

- Update image references to new filenames
- Clarify examples show same problem complexity with different scaffolding
- Emphasize scaffolding progression (full → medium → minimal → none)
- Add bold text to highlight key concept: constant complexity, varying support
