Till JS 1f2206f10b feat(cards-web): PDF input for AI generator + study activity heatmap ... PDF input: • lib/ai/pdf.ts wraps pdfjs-dist (Apache-2.0). Worker is bound via Vite's `?worker` suffix so the heavy parsing runs off-main-thread. • AiCardGen gains a "📄 PDF laden" button that pipes extracted text into the same textarea — the user can review/trim before generation. Reading state shows file name + page count + chars. Heatmap: • queries.useStudyHeatmap(weeks=12) fills gaps with count=0 so the grid renders without holes. • StudyHeatmap.svelte: 7 rows × N columns (Monday-anchored), 5 intensity buckets (neutral → emerald-300), tooltip per cell with date + count, legend strip. • Mounted on the dashboard between the deck list and the Anki import so the user lands on a quick visual progress receipt every visit.
