ljg-present 是做什么的?
Presentation Forger (Outline-Faithful). Renders orgmode/markdown outline levels 1:1 into visual slides—large colored blocks, ultra-bold offset text, leaving the original content untouched for beautification only. Three theme colors: black, red, yellow (default black or inferred from filetags). Can be explicitly overridden with -r/-b/-y; use --cyber for a black-background green-text cyber-hacker style. When used, the user might say: 'present this', 'present', 'make a presentation', 'show this', 'forge a presentation', 'make slides', 'slogan flow', 'manifesto style', 'slogan', 'manifesto', 'beautify by outline'. Outputs a single-file HTML to ~/Downloads/.
