Root cause

account.el declared el_img as a 1-arg extern (attrs: String). Every other file and the runtime C implementation use 3 args (src, alt, attrs). When the compiled binary tried to call the 1-arg variant, it passed garbage on the stack → signal 11 (SIGSEGV) on the first HTTP request. The TCP startup probe passed because the server bound to 8080 fine; the crash only hit on request processing.

Fix

Corrected extern declaration to el_img(src: String, alt: String, attrs: String)
Updated the one call site in account_nav() to 3-arg form

Test

Stage: /account should load (previously 503 on every hit)

account.el declared el_img with 1 arg (attrs only) while the runtime
implementation and all other files use 3 args (src, alt, attrs).
The arity mismatch caused the server to crash with signal 11 on every
request — TCP probe passed (bind was fine) but first HTTP hit segfaulted.
