Changelog

Navigation and discovery

• Primary menus now use real canonical routes for Generator, Guides, 3D templates and Learn, improving shareability, browser history and SEO.
• 3D templates opens the dedicated model page instead of jumping into the generator. The page presents predefined ruler/guide, roller, gauge and roller-accessory resources together with their explanations.
• Letter examples now scroll to the visible letterform reference section, and the home hero includes a direct action to the ready-made sheet presets.

Codes and reproducibility

• Code search results expose the decoded hand/script, nib type, nib width, x-height, nib angle and slant where available, so the result can be understood before opening it.
• Printed model codes keep the encoded physical revision. When a newer revision exists, the application explains the difference and lets the user reproduce the original or deliberately try the newer design.
• Printable sheets now carry an S1 sheet code, compact configuration metadata, a short /c/CODE URL and an offline-generated QR registration block in SVG/PDF exports.
• A dedicated Codes & revisions page explains durable codes, version history and why physical revision numbers are part of model identity.

3D tools

• Guide R4 adds six named trace-width profiles — 0.20, 0.35, 0.50, 0.70, 1.00 and 1.40 mm — plus a custom 0.15–2.55 mm throat. Historical R3 remains reproducible.
• Copy SCAD and Download SCAD remain visible while source code is collapsed; model-code lookup is intentionally secondary and includes an explanation of what the code is for.

• Introduced real section routes for the generator, guides, 3D templates, localized search and dedicated sheet/guide pages with canonical URLs and hreflang metadata.
• Added local, build-shipped site search, short code URLs, revision-aware model loading, responsive model controls and mobile routing fixes.
• Expanded 3D documentation with practical OpenSCAD rendering and slicer guidance, printable roller accessories and physical model registration.
• Added Shodō, Chinese calligraphy and Korean Seoye practice systems alongside the Latin broad-edge and pointed-pen workflow.
• Added feedback, privacy documentation, aggregate GoatCounter analytics and a shared public navigation system.

• Built the client-side parametric practice-sheet generator with broad-edge, pointed and monoline nib workflows.
• Added Uncial, Foundational, Italic, Textura and Copperplate presets with editable nib-width geometry, paper size, margins and slant guides.
• Added responsive beginner/expert help, visual nib references, SVG export, print-at-100% calibration and OpenSCAD ruler/guide, roller and nib-gauge prototypes.
• Added English, Spanish and German interface support and the first ready-made practice sheets.
