{#-
Site-wide additions. mkdocs-material emits a title, description and canonical
link, but nothing a link unfurler reads: without these tags Slack, Discord, X, LinkedIn
and iMessage render an AnyInfer link as bare text with a generic globe icon. Every value
is derived from the page itself, so each page unfurls with its own title and description
over the shared brand card (docs/assets/anyinfer-social-card.png, generated by
scripts/render_social_card.py).
Based on mkdocs-material 9.7.7 -- re-sync the block names on Material pin bumps.

when both are offered, plus the home-screen icon iOS uses (it ignores rel="icon"). -#}

takes the meta over on load. -#}
