Expand align from l/c/r to a 3x3 grid with vertical prefixes:
tl/tc/tr/bl/bc/br. Vertical position renders via flex
justify-content; compact layers strings and YAML both parse the
new values, and the layer editor dropdown gains corner/edge
options.
Accept yaml role=tag alongside legacy yaml/tag so the block
body gets yaml syntax highlighting, matching the CLI role=
attribute convention. Copy button now emits the role=tag form.
Replace per-axis x1/y1/x2/y2 layer fields with a single
pos string (x1,y1-x2,y2) matching the compact layers format.
When a deck is configured via a yaml/tag codeblock (data-config),
the copy button now emits a yaml/tag block serialized from current
store state so template layers round-trip.
Allow md-deck layers to render markdown templates via {{var}}
substitution instead of only CSV props. Add config.ts to normalize
a JSON data-config attribute (size, grid, shape, layers) emitted by
the yaml code-block tag, taking precedence over legacy string props.
Remove the `md-token` and `md-token-viewer` components along with their
associated 3D generation and image tracing utilities. Update
documentation and project metadata to reflect these changes and rename
the project title to "Tabletop Tools".
