literate: restructure all 19 org files with per-function blocks and prose
Every function, defclass, defstruct, defgeneric, defmethod, defmacro, defvar, and defparameter in every org file now has its own #+BEGIN_SRC block with literate prose above it explaining the design reasoning. Block counts before → after: package.org: 1 → 7 container-package.org: 1 → 1 (prose expanded) dirty.org: 4 → 6 render.org: 10 → 25 theme.org: 6 → 19 box-renderable.org: 9 → 29 scrollbox.org: 8 → 26 tabbar.org: 5 → 10 backend-protocol.org: 8 → 66 modern-backend.org: 17 → 53 detection.org: 4 → 6 layout-engine.org: 9 → 36 framebuffer.org: 8 → 37 markdown-renderer.org:13 → 38 dialog.org: 17 → 23 (merged dual structure) mouse.org: 4 → 25 select.org: 12 → 30 slot.org: 4 → 12 text-input.org: 11 → 53 Total: ~153 blocks → ~502 blocks Bugs fixed during restructuring: - render.org: stray π character typo (backenπd → backend) - modern-backend.org: sgr-attr missing closing paren + #+END_SRC - detection.org: invalid #\Esc character reference - select.org: extra closing paren in select-visible-options All 13 test suites pass at 100%.
