From 5ff3481cce56f40f15fa305b91f9ce26494909db Mon Sep 17 00:00:00 2001 From: Bryce Kwon Date: Wed, 15 Jul 2026 06:14:57 -1000 Subject: Reorganize into source, assets and libraries The C sources move to source/, the served files to assets/, the bundled Git submodule to libraries/git and the filter scripts to extensions/. Everything the build generates now lands in build/, so a clean is a single remove and the tree stays clean. --- .gitignore | 14 +- .gitmodules | 2 +- Makefile | 141 ++-- assets/cgit.css | 909
