// Build-time feature flags derived from board defines. Two flavours:
//
//   FEAT_* preprocessor macros — for conditional compilation of struct
//   members, enum entries, and class fields where the preprocessor must
//   run. Use `#if FEAT_X` instead of `#ifdef EINK_DISPLAY_MODEL`; the
//   name documents *what* the flag toggles rather than *why* it's bound
//   to e-ink.
//
//   Features::* constexpr values — for runtime-shape decisions (booleans,
//   timings, defaults). Compiler dead-branch-eliminates on the constexpr,
//   so cost is identical to a preprocessor branch but the code stays
//   reachable to tooling.

#if defined(EINK_DISPLAY_MODEL)
  // E-ink build: slow refresh, rotatable panel, no per-second redraws
  #define FEAT_BRIGHTNESS_SETTING         0
  #define FEAT_CLOCK_SECONDS_SETTING      0
  #define FEAT_DISPLAY_ROTATION_SETTING   1
  #define FEAT_JOYSTICK_ROTATION_SETTING  1
  #define FEAT_FULL_REFRESH_SETTING       1
