// THE SHADERS ARE REACHED BY IMPORTING A MODULE.
//
// `src/vulkan/render.cpp` opened with `#include "triangle_vert.h"` and
// `#include "triangle_frag.h"` -- two names no line in this project produced,
// and which no reader could derive without opening the rule. One import
// replaces both, and the accessors are named after the files:
// `shaders/triangle.vert` becomes `offscreen::shaders::triangle_vert()`.
//
// `module_name` is stated rather than defaulted so the module root matches the
// project rather than its directory: the package is `offscreen-triangle`, and
// the default would be `offscreen_triangle.shaders`.
