Four operator-reported issues from v0.4.67 validation.
## 1. NFS MNT3ERR_ACCES even with the host IP allow-listed
Root cause: Linux kernel nfsd (what UniFi UNAS / Synology / TrueNAS all
run underneath) exports with the `secure` option by default, which only
accepts mount/NFS requests from a privileged source port (<1024). v0.4.67
explicitly connected from a non-privileged port on the mistaken assumption
that uid 10001 can't bind low ports — but the binary carries
CAP_NET_BIND_SERVICE (granted via setcap for the DHCP/TFTP/HTTP low-port
binds), which also covers privileged *source* ports for outbound connects.
Fix: build_connection now tries a privileged source port first (the common
case for every appliance NAS), then falls back to a non-privileged port
for `insecure` exports or capability-less environments. Each attempt has
its own connect timeout; a timeout on the first attempt skips the fallback
(the server isn't answering — a retry would just double the wait).
Also: hint_for now recognizes MNT3ERR_ACCES distinctly from NFS3ERR_ACCES
and explains both the allow-list and the secure/insecure angle, with the
UniFi /var/nfs/shared/<share> path convention called out.
## 2. Custom logo didn't update the top-left brand mark
The brand <img> and favicon were pinned to ?v=<app-version>, which only
changes on upgrade — so uploading a new logo left the cached bundled SVG
in place. Added a monotonic `rev` counter to BrandingStore that bumps on
every set/clear, persisted across restarts, surfaced through index_html as
an extra &r=<rev> cache-bust token on the brand mark + favicon URLs. Since
index.html is served no-cache, the fresh token lands on the next reload
after upload and the new logo appears immediately.
(Note: this updates the WebUI brand mark. The PXE *boot menu* still shows
the ASCII wordmark — painting the operator's PNG there needs the
IMAGE_PNG-enabled iPXE rebuild that remains queued for native x86_64
hardware. The /branding/pxe-logo compositor is ready for when it lands.)
## 3. Disk-space card on the Dashboard
Extracted the Storage tab's disk card into a shared diskSpaceCard(disk)
helper and added it to the Dashboard grid under the stat strip. Dashboard
fetches /api/storage/disk with the same graceful-degradation fallback the
Storage tab uses.
## 4. NFS "Add share" button touching the form field
The NFS card has a single form row (vs SMB's two), so the button butted
right against it. Added margin-top:14px to match SMB's effective spacing.
Tests: 162 passing (+2 — logo_rev bump, MNT3ERR_ACCES hint). clippy clean.

Settings:
- New top-level Settings tab. Carries a placeholder for the planned
LDAP / OIDC / user-management work, the new branding controls, and
the API reference at the bottom.
- Custom logo upload (PNG/SVG/JPEG/WebP/GIF up to 2 MB) replaces the
bundled brand mark via /assets/logo.svg; bytes live at
<work_dir>/branding/ and survive restart. The original "OpenPXE
v<x.y.z>" pins to the sidebar footer for support.
- API reference rendered from a new GET /api/docs into a per-method
coloured pill list grouped by area.
ISO category (Storage):
- New IsoCategory { Os, Tools } on IsoMeta with PUT
/api/isos/:id/category. Storage table's Type cell becomes a
dropdown; selecting Tools moves the ISO into the Tools submenu next
to memtest / shell / NIC info and removes it from the OS Installers
family submenu. Family detection still drives BIOS/UEFI / kernel
args; only the menu placement changes.
Storage telemetry:
- New IsoStore::disk_usage (libc::statvfs, lives in iso-store so the
http-api crate stays #![forbid(unsafe_code)]) and GET
/api/storage/disk. The Storage tab now shows free/used/total for
the volume hosting the ISO directory with an 80%/95% colour ramp.
UI polish:
- Brand block in the sidebar now matches the topbar height exactly,
so the divider runs straight across the top of the app rather than
stepping; version label moved out of the brand and pinned to the
sidebar footer ("OpenPXE v0.4.4").
- Light-mode terminal: --terminal-bg + per-level text colours track
the active theme rather than being hard-coded dark.
- About: lead paragraph spans the full content width; new Docs row
links to https://openpxe.com/.
106 tests passing (was 89 in v0.4.1, +17 across branding unit tests
and new integration coverage for category / disk / docs / branding).
cargo clippy --workspace --all-targets clean.
