Rebuild wiki: teacher guides + technical reference Replaces the obsolete pre-fork pages (Code, Spreadsheet-Integration, Google-Cloud-Services — all described the old Google-Sheets version) with a full two-part wiki: For Teachers (non-technical): Quick Start, Managing Classes & Rosters, Daily Practice & Assignments, How Grading Works (with worked examples covering absences, enrollment proration, and section meeting exceptions), Work-Based Learning Guide, Importing Micro-Credentials, The DobbsCore Extension (install + every button). Technical: Architecture, Database Schema, API Reference, SAT Question Pipeline, Grading Algorithms, Extension Integration, Deployment & Auth, WBL Internals. Plus _Sidebar.md for navigation. Home rewritten as the landing page. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
