🏢 TunaOS Office Suite
A native office suite for GNOME — three apps written in Rust with GTK 4 and Libadwaita, sharing one document-engine foundation, distributed as Flatpaks.

Why this suite
- 🦀 Pure Rust engines — each app's document model lives in a
GTK-free core crate (
letters-core,tables-core,decks-core) with the UI as a thin shell. The formula engine is IronCalc; DOCX I/O is rdocx. - 📏 Measured LibreOffice parity, not claimed — every persisting feature is proven by tests that run our files through a headless LibreOffice in CI: 65 oracle tests, LibreOffice-authored corpora, and a CommonMark round-trip ratchet at 630/652. See PARITY.md.
- ⌨️ Powerful without clutter — a Ctrl+K command palette lists every action with its shortcut in all three apps; selection raises the formatting you need; status bars are live (word count and style in Letters, Sum/Avg/Count in Tables, slide/object readout in Decks).
- 🎨 GNOME native — libadwaita chrome, adaptive layouts, AT-SPI accessible; the smoke-test suite drives the apps through a screen reader's eyes on every push.
