/**
 * `gl.POINTS` glyph — one squared/antialiased point per data row. Color
 * and size are driven by the shared `a_color_value` / `a_size_value`
 * buffers; the vertex shader does sign-aware color-t mapping and samples
 * the gradient LUT. One draw call per series (the slot layout leaves
 * gaps at each series' tail that we can't safely include in a single
 * draw — dispatching `count[s]` per series skips them).
