;  SonosESP — PlatformIO project
;  ONE project, ONE codebase. Each SCREEN is a build environment ([env:...]) below.
;  Shared settings live in [env]; each screen only adds what differs (-DSCREEN_SIZE
;  + which panel driver to ignore). config.h resolves dims/pins from SCREEN_SIZE.
;
;     pio run -e esp32_4inch -t upload      # 4" (working)
;     pio run -e esp32_7inch -t upload      # 7" (PLACEHOLDER / WIP — see below)
;
;  `pio run` with no -e builds only the default (4") via default_envs.
;  See docs/MULTI_SCREEN_SUPPORT.md.
