# Preserves insertion order for the `dimension` map so ToJSON() emits

# here to use IndexMap in our own model types.

# Release profile tuned for WebAssembly SPEED (was size-first in ≤0.1.x).
# For a parsing/query library, runtime throughput matters more than a few KB of
# binary size, so we trade a slightly larger `.wasm` for faster code:
#   - `opt-level = 3`  → full speed optimizations (replaces size-first "s").
#   - `lto = "fat"`    → cross-crate link-time optimization (slower build,
#                        better runtime) — stronger than the plain `true`.
#   - `codegen-units = 1` → whole-crate single-unit codegen (best inlining).
#   - `panic = "abort"` + `strip` → trim panic machinery & symbols.
# wasm-pack still runs `wasm-opt` on top of this (see below).

# wasm-opt settings for `wasm-pack build --release`. `-O4` is the strongest
# speed-focused preset (replaces the balanced `-O`); current rustc emits the
# `bulk-memory` and `nontrapping-float-to-int` WASM features by default, which
# older bundled `wasm-opt` versions reject unless explicitly enabled, so we
# enable them here to keep `wasm-opt` running.
