Build failure in LeanPlot.ToFloat due to incorrect markdown header nesting

[motisn]

Description

When building the project with Lake, the build fails at LeanPlot.ToFloat because of a strict Markdown validation error in the documentation comments.

It seems there is a skipped header level (using ### without a preceding ##), which causes documentation tools like Verso/Subverso to crash the build.

Error Log

error: LeanPlot/ToFloat.lean:50:4: Incorrect header nesting: expected at most `##` but got `###`
error: Lean exited with code 1

Environment

Lean version: 4.31.0, x86_64-w64-windows-gnu

Thanks for the precise report. This was a real Verso/SubVerso validation failure: LeanPlot.ToFloat jumped from a level-one heading directly to ### Rat. PR #5 merged the minimal ### to ## correction as 55d17d2, preserving the contributor fix separately. Follow-up PR #8 updated main to Lean v4.32.0-rc1, ProofWidgets v0.0.104, and Verso v4.32.0-rc1, including the small docs-generator API adjustment required by current Verso. lake build LeanPlot.ToFloat, the full lake build, the 498-job docs build, and both Lean Action CI runs pass. Closing as fixed on main.
