## What happened

Installed Omarchy 4.0.1 from the ISO with no network connected. The install finished and
reported success.

Afterwards there was no VA-API driver on the system:

```
$ vainfo
vainfo: trying display: wayland
vaInitialize failed with error code -1 (unknown libva error), exit

$ pacman -Q | grep -iE "libva|intel-media"
```

The second command returned nothing. Only mesa, vulkan-intel and vulkan-mesa-implicit-layers
were installed. Nothing failed visibly during the install.

## What I expected

Video acceleration installed, or a visible failure if it can't be.

## Cause

`install/hardware/intel/video-acceleration.sh` runs:

```bash
omarchy-pkg-add intel-media-driver libvpl vpl-gpu-rt
```

Those aren't in the ISO's offline mirror. `/var/cache/omarchy/mirror/offline/` carries
`broadcom-wl`, `dkms`, `linux-headers`, the NVIDIA modules and so on, but no VA-API drivers.
With no network the call fails, and since the script has no `set -e` the install carries on
and finishes normally.

So this should hit any offline install on Intel graphics, not only this laptop.

The same pattern caught me earlier on a different machine.
`omarchy-install-service-tailscale` also has no `set -e`; its `omarchy-pkg-add tailscale`
failed offline, and the script's last line still enabled the `omarchy.tailscale` bar panel.
I ended up with a panel reporting "disconnected" and no tailscale binary anywhere.

## Reproduce

1. Boot the Omarchy ISO on a machine with Intel graphics, no network connected.
2. Complete the install.
3. Boot the installed system and run `vainfo`.

## Workaround

Once the repos were synced, the correct driver installed fine:

```bash
omarchy update
omarchy pkg add libva-intel-driver
vainfo   # Intel i965 driver for Intel(R) Haswell, 5 H.264 profiles with VAEntrypointVLD
```

Worth noting that `omarchy pkg add` fails with "target not found" until `omarchy update` has
run once, since a fresh offline install has never synced the pacman repos.

Two directions I can see: put the VA-API drivers in the offline mirror, or have the hardware
scripts report failures instead of continuing quietly.

## Secondary: driver selection on Haswell

Separate problem in the same file. I read this one rather than observed it, since nothing was
installed on my machine to fail in the first place.

```bash
if [[ ${INTEL_GPU,,} =~ (hd\ graphics|uhd\ graphics|xe|iris|arc|panther\ lake) ]]; then
  omarchy-pkg-add intel-media-driver libvpl vpl-gpu-rt
elif [[ ${INTEL_GPU,,} =~ "gma" ]]; then
  omarchy-pkg-add libva-intel-driver
fi
```

`intel-media-driver` (iHD) supports Broadwell and newer. The Iris 5100 in this laptop is
Haswell, Gen 7.5, and needs `libva-intel-driver` (i965) — which only the `gma` branch
reaches. An online install on Haswell-era Iris or HD Graphics would therefore install a
driver the GPU can't use. That's 2013-2014 Macs plus a good number of other laptops from
those years.

Happy to open that as its own issue, or to test something on this hardware if it helps.
