Changelog

Unreleased — 7 new features (built, not yet deployed)

Rebar shape codes (BS 8666): new Shapes input — pick a shape code (00, 20, 21, 32, 51, 99), enter dimensions, get the true cutting length with bend deductions, add straight into the optimizer.
Anchorage & lap length calculator (EC2): new Tools view — design anchorage l_bd and lap length l₀ per EN 1992-1-1 §8.4/§8.7 with all intermediate values shown.
Waste cost analytics: dashboard and results now show waste in kg and €, plus “€ saved vs simple next-fit cutting”.
Purchase order generator: printable supplier order from the cutting plan (bars per diameter × length, weight, per-supplier estimates), appendable to the PDF report.
Cost-optimal stock advisor: new Minimize toggle — waste or cost (uses supplier €/kg).
Share plan via link: copy a URL with the whole job encoded — anyone opening it can edit it. QR included.
Templates library: 7 one-click realistic jobs (stirrups, pads, columns, slab mesh, beams, cranks, starters).

Fixed a bug where stylesheet text appeared at the top of the page (a literal closing tag inside CSS comments was ending the stylesheet early).
Removed the "Install app" prompt: SteelCut stays a pure website, no installable app. Offline support is unchanged.

Exact optimizer: branch-and-bound for small jobs (automatically used when it fits), best-fit decreasing + first-fit decreasing for larger ones.
Cutting angle, saw kerf, trims, grip, end trim, and minimum reusable offcut — all accounted for in every plan.
DXF export of cutting plans for CAD workflows.
QR code piece labels for the workshop floor.
BBS import: paste a bar bending schedule and turn it into a cutting plan.
Stock advisor: suggests the best stock length to buy.
Efficiency report with numbered cutting sequence.
Excel/CSV import, quick text input, warehouse offcuts used first.
3-step wizard for new users + expert mode, 12 languages, mobile workshop styling.
Offline support (service worker) and full technical SEO (schema, hreflang, sitemap, robots).

Added el.html, a Greek landing page, plus sitemap.xml; submitted to Google Search Console.

Complete redesign in a light industrial style.
Multi-diameter optimizer, project & client info, PDF export, cut labels, dashboard & history.
Landing page with FAQ.
