Fix dark theme, animation speed, kitty opacity; add README

- libadwaita apps (nautilus, gnome-text-editor) rendered light because gsettings-desktop-schemas + dconf were missing, so the color-scheme prefer-dark autostart silently no-op'd. Add both packages. - Replace Hyprland's slow default animations with the reference laptop's bezier curves + per-leaf speeds (hl.curve + hl.animation). - kitty background_opacity 0.88 -> 0.6 to match the laptop; drop the macOS-only background_blur line (Hyprland supplies the blur). - Add README.md documenting the actual image, build, and test flow.

+# BOS — Bread Operating System
+
+An Arch-based, Hyprland desktop distribution that ships the [bread
+ecosystem](https://github.com/Breadway) preconfigured. One Calamares install
+produces a themed, bootable Wayland desktop — no manual Arch bootstrap, no
+wiring up dotfiles, no per-tool bakery installs.
+
+> Design rationale and the btrfs/A-B roadmap live in [DESIGN.md](DESIGN.md).
+> This file is the practical overview: what's in the image, how to build it,
+> and how to test it.
+
+## What you get
+
+- **Compositor**: Hyprland with a native-Lua config (`hyprland.lua`), curated
+  keybinds, snappy animations, blur, and pywal-driven colours on a black base.
+- **bread ecosystem**, baked into `/etc/skel` from bakery-managed binaries
+  (no network needed at install time): `bread`/`breadd`, `breadbar` (status bar
+  + notification daemon), `breadbox` (launcher), `breadcrumbs` (Wi-Fi profiles),
+  `breadpad` (notes/reminders), `breadman`, and the `bakery` package manager.
+- **bos-settings**: a GTK4 control panel that configures every bread\* app's
+  config from a GUI (non-destructively), plus snapshot rollback and bakery
+  updates. See below.
+- **Login**: greetd + tuigreet → Hyprland session.
+- **Boot splash**: Plymouth `bos` theme (logo + spinner, black background).
+- **Theming**: global dark across GTK3 (Adwaita-dark), GTK4/libadwaita
+  (`color-scheme: prefer-dark`), and Qt (qt5ct/qt6ct Fusion dark); Papirus-Dark
+  icons; Bibata cursor.
+- **Apps**: kitty, nautilus (+ gvfs), Zen browser, VLC, loupe, gnome-text-editor,
+  gnome-calculator, file-roller, with file associations wired in `mimeapps.list`.
+- **Hardware**: pipewire audio, NetworkManager, BlueZ + blueman, CUPS printing
+  with avahi mDNS discovery, TLP power management, fwupd firmware updates.
+- **Resilience**: btrfs + snapper + snap-pac + grub-btrfs snapshots on every
+  pacman transaction; zram swap; ufw firewall (deny-incoming, mDNS allowed).

+```
+
+## Building the ISO
+
+`build-local.sh` builds the image natively (no container) and bakes this
+machine's bakery-installed bread binaries into `/etc/skel`:
+
+```sh
+sudo ./build-local.sh              # release-quality (xz squashfs)
+sudo FAST_BUILD=1 ./build-local.sh # fast dev iteration (zstd squashfs)
+```
+
+The ISO lands in `out/bos-<date>-x86_64.iso`. The script pins
+`SOURCE_DATE_EPOCH` (reproducible UUIDs) and rewrites the `[breadway]` repo URL
+to the Tailscale-reachable Forgejo registry for the build.
+
+### Why some packages are in-house
+
+`calamares`, `zen-browser-bin`, and `bibata-cursor-theme` are AUR-only. BOS
+keeps a PKGBUILD for each under `packaging/` and republishes the built package
+to the `[breadway]` repo via a Forgejo Actions workflow (built on the hestia
+self-hosted runner, published with a scoped registry token). `bos-settings`
+itself publishes the same way on a `v*` tag.
+
+## Testing in a VM
+
+A reusable, GPU-accelerated launcher lives at `~/bos-vm/run.sh`:
+
+```sh
+~/bos-vm/run.sh install   # boot the ISO installer (target disk attached)
+~/bos-vm/run.sh           # boot the installed system from the disk
+```
+
+It uses KVM + `-cpu host`, 8 GiB / 8 vCPU, and `virtio-vga-gl` with
+`-display gtk,gl=on` (virgl) — 3D acceleration is essential for a smooth
+Hyprland session in QEMU. The disk lives on NVMe (not the tmpfs `/tmp`) to
+avoid memory pressure.
+
+## bos-settings
+
+`bos-settings` edits each bread\* app's TOML **non-destructively**: it parses
+the file with `toml_edit`, changes only the keys a view exposes, and writes it
+back — preserving comments and any keys the UI doesn't model (calendar
+passwords, saved-network passwords, model paths). Views:
+
+| View | Config |
+|------|--------|
+| bread | `bread/breadd.toml` — daemon, lua, modules, all adapters, events, notifications |
+| breadbar | `breadbar/style.css` override |
+| breadbox | `breadbox/config.toml` — launcher contexts |
+| breadcrumbs | `breadcrumbs/breadcrumbs.toml` — settings, saved networks, profiles |
+| breadpad | `breadpad/breadpad.toml` — settings, model + ollama, reminders, calendar |
+| Snapshots | `snapper` list / rollback / delete |
+| Packages | `bakery` installed list + updates |
+| Hyprland | open config in editor + monitor list |
+
+Build standalone:
+
+```sh
+cargo build --release -p bos-settings
+cargo test -p bos-settings        # includes config round-trip tests
+```
+
+## Boot architecture notes
+
+archiso keeps the kernel and initramfs outside the squashfs, so the installer
+stages them explicitly: a `shellprocess@kernel` step copies the kernel + ucode
+into the target `/boot` and writes a stock mkinitcpio preset before the native
+`initcpio` module builds the initramfs. GRUB is **not** installed by Calamares'
+`bootloader`/`grubcfg` modules (they leave the ESP empty in this layout) —
+`post-install.sh` runs `grub-install` (NVRAM **and** `--removable`) +
+`grub-mkconfig` instead, which is the sequence verified to boot.
