tanin-icons: accent-reactive folder icon theme (replaces Papirus)

New package packaging/tanin-icons/ generating 5 thin themes Tanin-<accent>
that inherit Adwaita and recolour only the folder/place ramp to the muted
Fuji accent (HSL shift keeping per-stop lightness; 16px rasterised so the
size-exact inherited blue PNG can't win).

- style.py: _set_gsettings now also sets icon-theme=Tanin-<accent_key> so
  folders recolour live with the accent.
- desktop.py: hide Tanin-* from the manual icon picker (accent-driven, a
  manual pick would be overridden on the next accent change).
- panel.py: pin-add icon hint Papirus -> Adwaita.
- build/finish-tanin-repo.sh: tanin-icons in OWN_SIMPLE; AUR rebuilds add
  librewolf-bin, arch-update, timeshift-autosnap, xdg-terminal-exec, paru.
- camel.toml: icon_theme=Tanin-<accent>, icons=[adwaita], tanin-icons own
  package + the new rebuilt_aur entries.

Deliberately excludes unrelated in-flight work (calendar/gtklock/
online-accounts/overview-backdrop) still uncommitted in the tree.

+# TANINUX — Handover (Session 2026-06-22)
+
+Context for a fresh instance. Repo: `~/projects/taninux` (distro codename **camel**,
+niri-only GTK4/libadwaita + eww desktop). User: Karim (German; iterates visually;
+hates UI jank; blanket perms in `~/projects`). UI strings are **English**.
+
+This session did two things: (A) added packages to the `[tanin]` binary repo,
+(B) built a custom **accent-reactive icon theme** to replace Papirus.
+
+---
+
+## A. New packages in the `[tanin]` repo
+
+The `[tanin]` repo is a thin overlay on Arch (own packages + AUR rebuilds),
+hosted on the Gitea Arch registry. Build/publish scripts in `packaging/`:
+`build-tanin-repo.sh` (no-sudo), `finish-tanin-repo.sh` (sudo: taninux + AUR
+rebuilds), `publish-tanin-repo.sh` (upload to Gitea).
+
+Added to the AUR-rebuild list (`build-tanin-repo.sh` + `finish-tanin-repo.sh`):
+- `librewolf-bin` — default browser. Also a **hard dep** of `tanin-desktop`.
+  ⚠ Security: rebuild + republish on every LibreWolf release, else `pacman -Syu`
+  ships a stale (vulnerable) browser.
+- `arch-update`, `timeshift` (+ `timeshift-autosnap`), `xdg-terminal-exec` —
+  all hard deps of `tanin-desktop` now.
+- `paru` — built into the repo but stays **optdepend** (not forced).
+
+Deliberately **rejected**: `papirus-folders` (removed). The other 20 AUR pkgs on
+Karim's machine are personal apps/games/emulators/hardware → not base-OS.
+`swayfx`+`scenefx0.4` are pulled by `greetd-regreet` (a leftover alt-greeter;
+TANINUX uses `tanin-greet`) — candidate for removal, not done.
+
+---
+
+## B. Icon theme: Papirus → `tanin-icons` (the main work)
+
+Karim's decision: Papirus is "too flat"; **Adwaita fits the design**, folders
+should follow the Fuji accent. The 5 Fuji accents are deliberately *muted*
+(`ume #8f8aac`, `shinkai #8a98ac`, `take #8aac8b`, `chikyu #aca98a`, `beni #ac8a8c`)
+— so `papirus-folders` (saturated presets) and native GNOME accent-folders (preset
+accents only) both can't match. Hence a custom package.
+
+**New package `packaging/tanin-icons/`:**
+- `recolor.py` — generator. Builds 5 thin themes `Tanin-<accent>` that
+  `Inherits=Adwaita`, recolouring **only** the folder/place icons. Algorithm:
+  HSL shift of the Adwaita blue ramp → keep each stop's **lightness**, swap
+  hue+saturation to the accent (preserves folder depth). White emblems untouched
+  (saturation gate). **16px PNGs are rasterised via `rsvg-convert`** because
+  Adwaita's only fixed-size raster is 16x16 — without an override the inherited
+  blue PNG wins at 16px.
+- `PKGBUILD` (depends `adwaita-icon-theme`; makedepends `librsvg python`) +
+  `tanin-icons.install` (gtk-update-icon-cache hook). Builds clean, ~52 KB.
+- ⚠ `recolor.py` was fixed to only `rmtree` its own `Tanin-<key>` subdirs, NOT
+  the whole `OUT` dir (it earlier wiped a shared dir when `OUT_DIR` pointed at
+  `~/.local/share/icons` — no data lost that time, but the bug is gone now).
+- ⚠ Rebuild this package after any `adwaita-icon-theme` bump (reads
+  `/usr/share/icons/Adwaita` at build time).
+
+**Integration (source only, NOT yet in the installed taninux):**
+`src/taninux/gui/style.py` → `_set_gsettings()` now also sets
+`icon-theme=Tanin-<accent_key>`, so folders recolour **live** when the accent
+changes. Also fixed `src/taninux/gui/pages/panel.py` hint "Papirus" → "Adwaita".
+
+**Wiring:**
+- `build-tanin-repo.sh`: `tanin-icons` added to `OWN_SIMPLE`.
+- `tanin-desktop/PKGBUILD`: depends `+tanin-icons`, **removed** `papirus-icon-theme`
+  (Adwaita is the base now), `pkgrel` 3→5.
+- Distro manifests synced: `distro/camel.toml` (icon_theme, `icons=[adwaita...]`,
+  new `[[packages.own]] tanin-icons`), `distro/MANIFEST.md` (icon row + pkg table).
+
+---
+
+## CURRENT STATE — read carefully
+
+| Thing | State |
+|---|---|
+| `tanin-icons` package built (`*.pkg.tar.zst`) | ✅ in `packaging/tanin-icons/` |
+| Verified GTK resolves folder @48px (svg) + @16px (png) to `Tanin-<accent>` | ✅ |
+| **Active in Karim's running session** | ✅ but via a **user-dir copy** at `~/.local/share/icons/Tanin-*` + `gsettings icon-theme=Tanin-beni` (current accent). NOT the pacman package. |
+| `tanin-icons` installed via pacman | ❌ (sudo needs a password; no TTY here) |
+| `[tanin]` repo rebuilt + published with the new pkgs | ❌ |
+| `taninux`/`tanin-desktop` rebuilt with the style.py change | ❌ → **accent→icon auto-switch is NOT live yet**; changing the accent in Settings won't move the icon-theme until taninux is reinstalled. Workaround now: `gsettings set org.gnome.desktop.interface icon-theme Tanin-<accent>`. |
+| ISO rebuilt | ❌ |
+
+So: **wired in source + manifests, but no artifacts rebuilt** → a fresh ISO/install
+does NOT have it yet.
+
+### To fully ship (needs Karim for sudo)
+1. `./packaging/finish-tanin-repo.sh` — builds `tanin-icons` + the new `taninux`/
+   `tanin-desktop` + AUR rebuilds.
+2. `./packaging/publish-tanin-repo.sh` — upload to Gitea (`TANIN_PKG_TOKEN`).
+3. Rebuild the ISO (pulls the updated `[tanin]`).
+4. Optional cleanup: once installed system-wide, delete the user-dir copies
+   `~/.local/share/icons/Tanin-*` (identical, harmlessly shadowed).
+
+---
+
+## OPEN / OFFERED, not done
+- **camel.toml `rebuilt_aur` list is stale** — still only eww/tiramisu/waypaper/
+  calamares/paru; missing `librewolf-bin`, `arch-update`, `timeshift-autosnap`,
+  `xdg-terminal-exec`. Offered to sync; awaiting Karim.
+- **Manual icon-theme picker** (`src/taninux/gui/desktop.py`) still lists the 5
+  `Tanin-*` themes and a manual pick gets overridden on the next accent change.
+  Could filter them out — not done.
+- **Accent-icon scope**: only folders/places are recoloured. Karim was asked
+  whether to extend to `emblem-*`/coloured mimetypes — undecided.
+- `papirus-folders` still *installed* on Karim's machine (`paru -Rns papirus-folders`).
+
+## Gotchas to respect
+- NEVER run lock/session/suspend commands to "test" (locked Karim out once).
+- GTK3 can't be exact-Fuji recoloured (parse-time `@define-color`); only GTK4/
+  libadwaita is exact. See memory `taninux-gtk-theming`.
+- Lots of unrelated uncommitted changes exist in the tree (tanin-calendar,
+  online_accounts, gtklock, iso/*) — NOT from this session; don't bundle them.
+
+## Files touched this session
