struct	bb::ecc::booth::BoothSliceParams
	Per-window precomputed slice parameters for the carry-less signed-Booth window recoding. Read out by the per-(point, window) hot loop as two i32 loads + a fixed bit-twiddle (no branches, no per-iter address arithmetic). More...

Functions
constexpr BoothSliceParams	bb::ecc::booth::compute_booth_slice_params_unchecked (size_t bit_offset, size_t window_bits, size_t num_uint64_limbs) noexcept
	Compute the Booth slice params for a window starting at absolute bit position `bit_offset`. The slice is `[bit_offset - 1, bit_offset + window_bits)`; the bit at `bit_offset - 1` is the shared boundary bit. The bottom window (`bit_offset == 0`) is encoded specially so the same recoding algebra applies — read "limb -1" as a zero-masked load.

uint32_t	bb::ecc::booth::booth_packed_digit (const uint64_t *s, const BoothSliceParams &sp, size_t window_bits) noexcept
	Read a (window_bits+1)-bit window from `s[]` (uint64 limbs) and apply Constantine's signedWindowEncoding to produce a `(sign \| magnitude)` packed digit: bit 31 = sign (1 = negative), bits 0..30 = magnitude in [0, 2^(window_bits-1)]. Magnitude 0 means the window contributes nothing.
