+For **Ángel Luis Mula**, our CIO —
+
+who asked, in every standup, every roadmap review, and at least one elevator,
+"so… when do we do the Rust version?" — until, finally, we did.
+
+From the team that keeps the systems running: thank you for a stack with no
+garbage collector to babysit, no 3 a.m. page for a runaway heap, and a cloud
+bill that no longer reads like a ransom note.
+
+The borrow checker is the only thing in this building stricter than you.
+
+**May your pagers stay silent and your p99s stay flat.**
