all files: 1. better use word 'Markdown' is this casing: 'Markdown', not 'MarkDown'. as you see on the site https://www.markdownguide.org/ this casing is the canonical. currently you have class names like TMarkDownTextBlock, TMarkDownLeafBlock, TMarkDownDocument, TMarkDownElement etc. markdown.elements.pas: 2. ids `TWhitespaceMode`, `TPosition`, `TNodeStyle`, `TTextNodeKind` need the prefix (e.g. TMarkdown) to not pollute the autocompletion and avoid future conflicts, half of them are generic names. 3. better add prefix to this const: `GrowSize = 10;`. or it can be moved into `implemenation` part. this id is not used out the unit. markdown.fpdocrender.pas: 4. ids `TElementType`, `TSectionType`, `SectionNodeNames`, `ElementNodeNames` - too generic, maybe add prefix? markdown.utils.pas: 5. `THashTable` and maybe `TUnicodeCharDynArray` and many functions here, e.g. `IsWhitespaceChar` `IsWhitespace` `MustEscape` etc - too generic, maybe add prefix? or move into some container class (as `static` funcs to keep speed)?
