zeekay 8fd4fd4bd9 Drop the catalog's expired artwork urls; artwork is served from our own origin
All 457 icon and screenshot urls across all 202 apps were presigned links to a
single bucket, signed 2025-11-05 with X-Amz-Expires=86400. They have answered
403 ExpiredRequest since the day after, and a presigned url cannot be re-signed
by whoever holds it, so the images are unrecoverable through the only address
anyone had for them and no copy exists elsewhere. There is nothing to re-host.

A url that cannot resolve is not artwork, it is an outbound request that always
fails, so the fields are removed rather than repointed. AppIcon already renders
the initial when icon is absent and the Screenshots panel already hides on an
empty list, so the page looks the same and loses 202 failing requests and 245 KB
of catalog per visit: store.json goes 494 KB to 249 KB.

Artwork is served from this site's own origin as a root-relative path. data/ is
the one source both generate-store.js and the hanzoai/cdn market build copy from
verbatim, so the rule holds in one place.

"name": "PPTX content extractor with OCR and audio lesson generator",
"description": "This tool extracts text from a PowerPoint presentation, creates a lesson text about it, and generates an audio file of the lesson. It extracts content slide by slide and shape by shape. It uses OCR to extract text from image shapes (using Tesseract). It generates a detailed lesson text about the PPTX using a LLM and optional additional instructions. Optionally, it generates a mp3 audio file of the lesson using ElevenLabs text-to-speech. This tool requires Tesseract to be installed for OCR. It also requires the tool “ElevenLabs Text to Speech” from the Hanzo AI Store, and an API key for ElevenLabs text-to-speech if choosing to generate audio files. You can download Tesseract from here : https://github.com/UB-Mannheim/tesseract/wiki. You can get an ElevenLabs API key here : https://elevenlabs.io/developers.",
