New module math_assist.rs: when the last two strokes form an = and the pen
rests for 500 ms, the strokes left of it (in a band around the =, up to a
wide gap) are recognized and computed. The suggestion appears next to
the = and shows what was read, e.g. "2⁴ = 16"; tapping it with the pen
or clicking inserts the result as a text box in the ink color and as high
as the handwriting, as one undo step. The chip is not interactive for
egui, so fingers and palms pass through. Any new stroke drops it. In a
chain like x = 2 · 3 = the part after the previous = is computed.
Off by default: ☰ → Input → "Compute formulas after =", saved in
ui.json. math::display writes the recognized expression neatly.

Shared groundwork:
- paths.rs: folders for data, settings and downloads per system (Linux XDG
unchanged, Windows %APPDATA%/%LOCALAPPDATA%, Android app folder)
- Linux-only parts behind cfg: Wayland on-screen keyboard (osk/wayland.rs),
display backend and app id, the vendored winit touch extensions
- run_with(event_loop) so that other entry points can start the app
Windows (#48):
- cross-compiled with MinGW into a portable ink-notes_<version>_x86_64.exe
(system DLLs only), no console window in release builds
- file picker: user folders and drives; held notebook locks are detected
(ERROR_LOCK_VIOLATION)
- updater: replaces the running .exe via rename, active at the next start
- octotablet panicking without the Tablet PC components no longer crashes
the app
- release: .exe built in CI and part of the signed checksums
- all library tests pass under wine
Android (#42):
- android_main entry point, winit with android-native-activity,
android_logger; octotablet and arboard left out there
- cargo check and the cdylib build for aarch64-linux-android pass; the window
surface does not follow the activity lifecycle yet

- Storage location setting: the notebooks can be moved into a folder kept in
sync by Nextcloud, Google Drive, Syncthing etc. (subfolder `ink-notes`);
existing notebooks are copied there if it is still empty, the originals stay.
- Changes from other devices are taken over while everything local is saved:
changed pages are reloaded, new/removed/reordered pages and titles come in
through the manifest. A page file still being synced is retried later
instead of being set aside as damaged.
- Conflict copies made by sync clients become pages of their own.
- `.opened_by.json` marks the device that has a notebook open; opening a
notebook open elsewhere shows a warning.

The import now also accepts Saber files: .sbn2 (BSON) with its asset
files next to it, .sba archives (zip with main.sbn2 and assets) and the
old JSON .sbn, including the layout before format version 8 with
strokes outside the pages. Taken over: strokes with pen pressure and
perfect_freehand's thinning, highlighters, circle and rectangle shapes,
typed text (Quill delta as one text field), images (SVG rasterized),
background images and PDF pages as PDF backgrounds, paper patterns.
BSON and zip are read by small built-in readers, so no new
dependencies. The SVG rasterizer moved to src/import.rs.

The import (menu entry and drag & drop) now also accepts .rnote files
from Rnote 0.5.10 on, including the transformation and document config
layouts that changed in 0.13 and 0.15. Taken over: brush strokes with
their pressure curve, shapes as outlines, texts, bitmap images and SVG
images, which are rasterized with resvg (Rnote stores imported PDF
pages as SVG). Fixed-size and continuous documents keep their pages;
infinite ones become an endless notebook.
The parts shared with the Xournal++ import moved to src/import.rs.
resvg and its dependencies were added to the Flatpak cargo sources.

The import menu entry (formerly "Import PDF") and drag & drop now also
accept .xopp and .xoj files. Each Xournal page becomes a page of a new
notebook: strokes with pen pressure, highlighters, texts, embedded
images, lined/squared/dotted paper, image backgrounds and PDF
backgrounds (looked up at the stored path and next to the file). All
layers are flattened in order; LaTeX formulas are skipped and counted
in the status message.

- #38: the eraser size button opens a menu like the pens: four presets and a slider
(2–30 mm diameter)
- #41: shape corners stay pointed down to about 14° (miter limit 8 instead of 2)
- #40: page picker tiles are as high as the tallest page needs, so slides get flat tiles;
the frame follows the page instead of the whole tile
- #28: the fling diagnosis also logs finger starts, mouse buttons and wheel/touchpad events

- #41: snapped triangles, rectangles and polygons keep the full stroke width on every
side; corners are mitered, sharp ones bevelled (the old corner offset thinned the edges)
- #38: four eraser sizes, cycled by a button below the eraser modes and remembered in
ui.json
- #37: a selection made with the pen's select button can be moved with the bare pen
- #39: fingers resting on the screen when the pen comes near, or touching it while the pen
is near (and 0.7 s after), are ignored until lifted; the vendored winit ignores touches
on the title bar meanwhile
- #40: the page picker shows imported PDF pages, rendered small in the background

A 👁 button below the notebooks hides the tools. Pen, finger and mouse
then only scroll and zoom (the pen glides on like a finger), editing
shortcuts are ignored, Page Down no longer appends pages, and selection,
text box and ruler are closed when entering the mode.
The toolbar size estimate now includes the measured frame overhead and
can shrink buttons to 26 px, so the extra button still fits at 768 px.

Ein endloses Notizbuch hat eine einzige Seite von 10 × 10 m; Eingabe,
Treffertests, Undo und Speichern bleiben dadurch unverändert. Die
Ansicht zeigt bei 100 % einen DIN-A4-Rahmen in der Mitte, Bilder und
Textfelder richten sich nach A4. Wählbar beim Anlegen und im ☰-Menü,
umschalten nur bei einer Seite ohne PDF bzw. zurück, solange alles im
Startausschnitt liegt. Seiten-Knöpfe sind auf der endlosen Fläche aus.
Der Export enthält nur den beschriebenen Bereich mit 10 mm Rand, auf
das Musterraster gelegt; Bilder einer Auswahl rastern nur noch den
Ausschnitt statt der ganzen Seite. Formatversion 9.

Ob ein Notizbuch Seite für Seite oder durchgehend angezeigt wird, steht
jetzt im Manifest (`layout`). Beim Anlegen ist „Feste Seiten“
vorgewählt; im ☰-Menü lässt sich die Anordnung des offenen Notizbuchs
umschalten. Notizbücher ohne Angabe behalten die frühere globale
Einstellung, ältere App-Versionen ignorieren das Feld.

Im Tablet-Betrieb gibt es keine Umschalttaste. Beim Auswahlwerkzeug
steht unter den Stiftfarben jetzt ein Schloss: 🔒 skaliert gleichmäßig,
🔓 frei. Vorgabe ist gesperrt, sobald ein Bild ausgewählt ist, sonst
frei. Das Umschalten gilt für die aktuelle Auswahl; eine neue Auswahl
beginnt wieder mit der Vorgabe. Shift sperrt am Rechner zusätzlich.

- packaging/flatpak/eu.pansi.ink-notes.yml: Runtime freedesktop 26.08,
Rust aus rust-stable, Abhängigkeiten offline aus cargo-sources.json.
Rechte: Wayland/X11, GPU, Lesen von Bildern/Downloads/Schreibtisch,
Schreiben in den Dokumente-Ordner (kein Zugriff auf den ganzen
Home-Ordner).
- Im Flatpak sucht und installiert ink-notes keine Updates selbst
(Vorgabe von Flathub); der Update-Dialog verweist auf die
Software-Verwaltung.
- Export-Ordner aus user-dirs.dirs (z. B. ~/Dokumente) statt fest
~/Documents; nur dieser Ordner ist im Flatpak beschreibbar.
- Metainfo und Desktop-Datei auf Englisch mit deutscher Übersetzung,
Release-Einträge, unterstützte Eingabegeräte.
- Test: cargo-sources.json deckt Cargo.lock ab.

Alle Oberflächentexte und Fehlermeldungen stehen in t!("…"); der deutsche
Text ist zugleich der Schlüssel für die englische Fassung in
src/i18n/en.rs (430 Einträge). Platzhalter heißen {name}. ink-notes folgt
der Systemsprache (Deutsch bei de…, sonst Englisch); im ☰-Menü lässt sie
sich unter „Sprache / Language“ auf System, Deutsch oder English
festlegen, gespeichert in ui.json.
Ein Test prüft, dass jeder markierte Text übersetzt ist, keine
Übersetzung verwaist und die Platzhalter übereinstimmen.
Konsolenausgaben bleiben deutsch.
