templates.js and renderer.js content extracted via direct line-slicing (not retyped) given their size (~660-line HTML/CSS template functions) -- avoids transcription risk on template-literal-heavy code. Verified via smoke-test harness (28/28 match). server.js: 4492 -> 3784 lines (6838 originally -- 45% reduction so far).
