From ba2d7ae1d7b319645b10aaa31a7f664f9f80c25c Mon Sep 17 00:00:00 2001 From: user Date: Sat, 18 Jul 2026 00:38:38 +0200 Subject: refactor: c/ -> usr/, compiled program blobs out of the source tree Userland sources live in usr/ (fits the Unix theme better than 'c'). SDCC output .bin blobs land in build/usr/ with the other build artifacts instead of littering the source dir; programs.asm INCBINs them from there.
