From 4fb28be16302bc8e912f8df36bb34bcac4b9b99e Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 23 Jun 2026 19:33:14 +0000 Subject: [PATCH 1/4] feat: refactor architecture to Narrative Code & Hexagonal Core - Extracted domain logic to src/domain/ (blog, transitions, accessibility, tools). - Deconstructed God Classes (TransitionController, AccessibilityManager) into pure functions. - Implemented SLAP-compliant functions and business-focused naming. - Added comprehensive unit tests for all domain modules. - Updated AGENTS.md with new coding standards.
