Inside-LMS toolbox for registered students: callout-CSS, YAML-frontmatter,
theme CSS-variables, Style Settings generators. Auth inherited from (student)
route group; no public surface, no email gate.
- Pure generators in src/lib/tools/* with Vitest (33 tests)
- Shared YAML-safe scalar quoter (_shared/yaml.ts) used by frontmatter +
style-settings: unquoted user input was silently breaking YAML (tags '#x'
-> null, color default '#7C3AED' -> null, 'a: b' -> parse error)
- hex validation in callout (no NaN), date input constrained, clipboard +
analytics calls guarded
- Prisma ToolUsage model + migration; logToolUsage Server Action (auth-first,
10-min dedup window per user/tool)
- Tool index /tools + ToolCard (explicit lucide map, no import *) + header link
