The ~800 MB trim (glibc langpacks en-only + linux-firmware strip to the i915
keep-list, run pre-dracut) builds and boots — the boot/root path survives it
(firmware 678->147 MB, initramfs bundles only the keep-list). Notes still-open
checks: kiosk RENDER on real i915 hardware ('booted' != 'display up'), and that
the two later commits (nss-mdns drop 5cc72cc; omit_drivers + keep-list tightening
853ae20) are NOT in f59eb79 and need separate bench-verify.
