// Shared helpers for the EquityFinancialsTab partial-class split.
//
// Both `EquityFinancialsTab_Views.cpp` and `EquityFinancialsTab_Populate.cpp`
// need the same color constants, frame builders, table factory, and chart
// view factory. Defining them at file scope inside each TU works under
// non-Unity builds but causes ODR violations under Unity concatenation.
//
// Placing them here as `inline` (C++17) gives them a single canonical
// definition across translation units while keeping them inline-able.
