Particle Library 0.1.1

Follow-up preview for macOS and Android.

New

Full backup / import — one ZIP with settings, favorites, notes, highlight
anchors and cached review PDFs. Import auto-detects the backup, merges notes
without deleting current data, and preserves the Apple Supporter entitlement.
Export is available on desktop; mobile builds can import.
Full catalog everywhere — the catalog is reachable from every primary tab
(top bar on desktop, overflow menu on compact layouts).
Apple-only Supporter UI — a $0.99 non-consumable supporter badge prepared
for App Store builds. It is hidden on Android and in the ad-hoc macOS build
until an App Store product exists. Core features stay free.
Editable highlight ranges — tapping a highlight selects it and exposes
the two drag handles directly; save with the check button. Renamed highlight
titles survive range edits.
Better update checks — jsDelivr/raw GitHub manifest fallback for networks
where the GitHub API is blocked, with update.json as the release manifest.

Spaced exotic-particle descriptions such as T_c c cbar cbar(6600) stay one
math unit; prose suffixes such as MASS/MEAN LIFE are no longer swallowed
into subscripts.
Neutral charge-zero shorthand (B_s0, Xi_c0, Lambda_b0, …) renders as a
superscript, consistent with particle-symbol rendering.
Reference titles clean JATS/MathML/MathML-namespaced markup, including
pretty-printed MathML, square roots, fractions and superscripts; literal
comparison signs such as <sqrt(s)< are preserved.
Approximate masses use \sim; decay multiplicities no longer gain a comma;
text-only decay tokens containing arrows are preserved.
PDF highlight notes use the human review title in generated titles and bodies;
comment/range edits no longer revert to the PDF filename.
Anchor removal is persisted immediately and on close.
Deleting a highlight asks for confirmation; desktop selection handles are
enabled.
Full catalog entry, title clamping/identifier-first defaults and several
reference-title surfaces no longer show raw MathML/HTML.
Android manifest no longer requests the Billing permission (Supporter is
Apple-only).

macOS DMG/ZIP rebuilt from this tag; Android arm64-v8a and armeabi-v7a APKs
rebuilt with the same snapshot.

macOS preview is ad-hoc signed, not notarized.
iOS is development-signed only; App Store distribution needs a paid Apple
Developer team and a configured Supporter product.
Android API 24 and 32-bit devices are built but not device-tested in this
release.
Full-backup export requires the desktop file picker; mobile can import.
Supporter purchase is hidden until the App Store Connect product exists.
