The Day Before Launch, I Overhauled Performance — And One Thing I Never Fixed

What I Added Beyond AstroPaper Defaults — Running a Blog Like a Product
This blog doesn't leave AstroPaper as-is — I keep expanding it from the perspective of a 'daily-publishing solo content system.' A record of what problems I hit and how I turned them into tools — series page (collapsible) · playground · KR/EN i18n · Sonnet 5 translation automation pipeline · internal/external link checker · local Mermaid pre-rendering · Scratch/Inbox workflow · convention for auto-hiding ended projects · security scrubbing guidelines · post-hoc markdown validator · editorial redesign that removed the sidebar · a publishing heatmap that updates daily on a static site · outcome-first portfolio cards. Each feature follows a 3-part structure: 'what was missing in the default state → how I solved it → the result.' A living document, so it will keep expanding as new features are added.
