Changelog

Features

• Appearance settings: an accent-color wheel that re-tints buttons, links, and highlights across the whole app live, plus a background picker (6 built-in ambient artwork presets, or upload your own image) — both saved on-device
• A real favicon, replacing the default Next.js placeholder

Improvements

• Every color token now derives from a single --accent-hue CSS variable instead of being hard-coded, so the theme wheel can re-tint the entire UI, not just one button

Fixes

• Homepage was silently serving the default create-next-app starter page instead of the real Latticework landing page — a leftover, never-edited src/app/page.tsx was shadowing the real one at the same URL

Features

• CLI-simulation exercises: a new in-browser Unix-shell sandbox (navigation, file ops, pipes, redirection, variables, permissions, sort/uniq, a grep/sed/awk subset) — brings the Bash, Terminal/CLI, and Linux courses to life for the first time

Improvements

• Skill catalog coverage: 77 of 99 technologies now have real interactive lessons, up from 74

Features

• Career roadmap engine covering 11 tracks with a dependency-ordered skill graph
• Interactive Python course (Variables, Loops, Functions) with in-browser sandboxed execution
• XP, mastery/skill-rating engine, spaced repetition, and streaks
• AI tutor hint ladder (4 levels, OpenAI-compatible provider)
• Onboarding flow with a short diagnostic and personalized first-skills recommendation
• 98-technology skill catalog (Explore page + skill graph), most as structured skeletons
