/* SELF-HOSTED POPPINS (REQ-THRESHOLD-0003) — the wordmark/UI specify Poppins;
we embed it rather than relying on a system fallback. Enclosed-app safe: the
fonts are LOCAL, subsetted woff2 files under media/fonts/, referenced by a
RELATIVE path (no external font URL). Built by build_poppins_fonts.py from the
installed Poppins TTFs. The 700 face covers weights 700–900 so the wordmark's
font-weight:800 resolves to real Poppins Bold (no faux-bold synthesis). */
