// Build-time feature flags derived from board defines.
// Use these instead of `#ifdef EINK_DISPLAY_MODEL` 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
// remains readable and reachable to tooling. Conditional struct members
// (enum entries, NodePrefs fields) still need a real `#if defined(...)`.
