// Scalar double exp2 — structural sketch of the dump function at 0x18026b820
// (element kernel wrapped by bigkernel 0x18026c220). NOTES_LEVEL:854-860.
//
// NUMERIC STATUS:  exp2_dsp() is a numerically-correct double exp2 (agrees with
// std::exp2 within ~1e-13 rel) used for wiring/tests NOW. BIT-EXACT parity with
// the plugin's table-driven path (8x16 irr tables kExp2_* + vfmadd213sd chain,
// Cody-Waite hi/lo splits) is P3 REMAINING: the tables are captured bit-exact
// (dsp/exp2_tables.*), the algorithm wiring is not yet transcribed 1:1.
