+# ── Release profile — wheel size optimization ───────────────────────
+#
+# PyPI imposes a 10 GB cumulative storage limit per project. We hit it
+# at version 0.21.36 (191 versions × ~213 MB/release = 10.00 GB
+# exactly). Recent wheels were ~16-18 MB each, of which ~6.4 MB was
+# pure debug metadata (`.strtab` + `.symtab` ELF sections; uncovered
+# by post-mortem inspection of an actual production wheel).
+#
+# This profile shrinks each Linux wheel from ~18 MB → ~10-11 MB by:
+# * Stripping symbol/string tables (~6.4 MB direct savings)
+# * Link-time optimization across crate boundaries (~5-10% .text
+#   savings via dead-code elim across the workspace)
+# * Single codegen unit (better inlining + dead-code elim, at the
+#   cost of slightly slower release builds)
+#
+# We deliberately do NOT set ``panic = "abort"``. The proxy is a
+# long-lived async process — a single misbehaving request triggering
+# panic-abort would terminate the whole proxy and disconnect every
+# concurrent client. Accept the smaller savings; keep unwind behaviour.
+#
+# Estimated impact: 213 MB/release → ~130 MB/release. Buys ~30+ more
+# release slots within the 10 GB ceiling at the current release
+# cadence. Per-PyPI-version savings AND faster downloads for end
+# users. Tradeoff: release builds take ~30-50% longer due to
+# `codegen-units = 1` + LTO; acceptable for the size win.
