admin 317037f8eb scripts v1.22.0 — ISO boot screen + single-entry GRUB menu (R-38 GRUB slice)
Two jobs, one repack pass.

BRANDING. Every ISO now carries a Felhom boot screen built from the website's
og-image_2.png at repack time (ImageMagick in the assistant container), so the
boot card has ONE source and not a second pre-rendered copy in the repo to
drift. The card is scaled onto a 1024x768 gfxterm canvas, top-centered, and the
card's own subtle background grid is continued across the letterbox fill
PHASE-LOCKED to where the card's grid lands — the fill is seamless rather than a
square of grid floating in flat navy. Menu positioning needs a gfxmenu theme
(plain background_image cannot move the menu off the wordmark), so the stock
pvetheme is replaced by felhomtheme, which puts the menu in the lower third the
layout deliberately leaves empty.

SAFETY — the half that matters. The stock PVE menu offers Graphical, Terminal
UI and serial installers plus an Advanced Options submenu (nomodeset x2, three
debug variants, Rescue Boot, memtest, UEFI settings). Every one of them reaches
the MANUAL installer, whose first question is which disk to wipe. A customer, or
their helpful nephew, must not be able to get there from a boot menu. They are
not hidden and not password-gated: they are NOT EMITTED. What ships is one
entry, 'Felhom telepítés', default, 5s.

Boot behavior is unchanged. The kernel/append and initrd lines are lifted
VERBATIM from the ISO's own 'Install Proxmox VE (Automated)' entry rather than
frozen into a copy here, so a PVE bump tracks automatically; the build fails if
they cannot be found, if the append line has lost proxmox-start-auto-installer,
or if auto-installer-mode.toml is absent (which would mean the one Felhom-
labelled entry boots a manual installer). The rendered menu is then gated for
exactly 1 entry, 0 submenus, and zero references to proxtui/proxdebug/nomodeset/
Rescue Boot/memtest/fwsetup — and re-verified by reading the menu back OUT of
the finished ISO, not merely out of the extract tree.

mkimage-surgery.sh -> iso-repack.sh: branding and the slice-B loader swap need
the same extract -> modify -> re-master cycle, so they share one pass instead of
re-mastering twice. The mkimage recipe is untouched. The embedded module list is
still derived from the STOCK grub.cfg (snapshotted before branding rewrites it),
plus gfxmenu's bitmap/bitmap_scale/trig renderer deps.

# Felhom ISO — GRUB gfxmenu theme (scripts v1.22.0, R-38 GRUB slice).
#
# WHY A THEME AND NOT `background_image`: plain gfxterm draws the menu in the terminal's own region
# (top-left), which on our card lands the text straight across the cloud/wordmark. A gfxmenu theme is
# the only way to POSITION the menu, so the menu sits in the clean lower third that
# generate-grub-background.sh deliberately leaves empty (the card is composited into the TOP 516px of
# a 1024x768 canvas). Keep this file and the background generator's CARD/CARD_Y constants in sync —
# if the card grows, `boot_menu.top` must move down with it.
#
# Colors are design-system v2: --blue #0083D8 for the selected item, light text on the near-black
# navy (#0D1117) the card itself uses.
