feat(cards): image / audio attachments on cards via mana-media
Cards can now carry image, audio, and video attachments uploaded to
mana-media (the existing CAS service that already powers picture,
photos, wardrobe, etc.).
Pipeline:
• lib/media/upload.ts wraps POST /api/v1/media/upload (multipart,
app=cards). Returns { id, url, kind } with the right variant URL
per kind (medium for images, full file for audio/video). 25 MB
cap matches the website-upload pattern.
• mediaToFieldSnippet(): drops Markdown ![]() for images; raw
<audio>/<video controls> for the others — the user can later
tweak attributes by hand.
• Deck-detail card editor gains a "📎 Anhang" button next to every
text field (front/back/cloze). Pick → upload → snippet appended
to the field's content. Loading + error states surfaced inline.
Render:
• @mana/cards-core/render.ts whitelists `audio`, `source`, `video`
plus the `controls`/`preload`/`src`/`type` attrs in DOMPurify so
inline media survives sanitization. Markdown's <img> already
passed through the default policy.
Wiring:
• hooks.server.ts injects __PUBLIC_MANA_MEDIA_URL__.
• compose adds PUBLIC_MANA_MEDIA_URL_CLIENT=https://media.mana.how
to cards-web.
Phase 2 ideas: drag-drop directly into the textarea, paste-from-
clipboard for screenshots, mana-media auth scoping per user, Anki
import bringing media files along.
