The scene template center was a fixed 720x554 dialog centred on the canvas
region, which a 240px rail visibly pushed off the window's centre. It now
insets from the whole viewport under a full-window scrim, flows 2/3/4
columns by width with card heights derived from a 16:10 preview (the old
0.62 cap that letterboxed every preview is gone), caps the content column
at 1680, and ships previews rebaked at 1024x640.
Template cards grow two actions: "add to canvas" appends the template's
boards into the current document in one transaction — template variables
are namespaced per template so two decks can no longer recolour each other,
and batch insertion no longer swallows a pre-existing empty root — while a
pristine starter still opens the template directly. "Generate from this"
pins the template's style guide, narrows the scene filter, and focuses the
topic field behind a clearable "based on" chip, so the existing pipeline
generates in that template's look. The web host also gains the missing
open/adopt drain; clicking a template there previously did nothing.
