…n CSS in smoke test New themes: - 14-diagramforge-cyberpunk: neon-noir dark theme (near-black bg, hot-pink/cyan/purple accents) - 15-diagramforge-synthwave: retro-future dark theme (deep-purple bg, sunset-orange/hot-pink accents) Each includes a CSS file and companion smoke-test Markdown deck with lead, accent, neon/sunset, and compact class variants. Fix: Invoke-PptxSmokeTest.ps1 now auto-detects a companion .css file when -ThemeCss is not explicitly provided, matching the behavior already present in Invoke-AllPptxSmokeTests.ps1 and Generate-SamplePptxSet.ps1.
