// This is an example of a 'curtain' page transition for nextjs app router
// when hijacking the <Link /> to set valio's pageTransitionState.requested = href; 
// I start off a transition process, switching out the the page when the curtain is closed
// I quite like the way each pass resolves the value from mapCurtain01Props, feels tidy.

# This is an example of a fabric texture (for 3d models) download client I created for a Python / Django site,
# 1. when a user requests a texture download, it creates a task using Celery,
# 2. this task creates a RequestTexture item in the database
# 3. if the textures have never been requested before - 
#    it retrieves the texture images (presigned files that expire) from an external bucket 
# 4. once I have selected and pulled them to a temp/ folder I zip them up (with spec sheet pdf)
# 5. optionally (on the server, or locally if USE_AWS_S3_MEDIA is set) I push them onto our bucket
# 6. lastly, I send an email to the download view, which triggers an automatic download

# - when we call get_cart / get_checkout (not is_order)
# - a. last_price_revalidation is greater than
