open_board — ALWAYS call this first when given a board URL or ID.
create_board — Create a fresh board in ONE call — optionally pre-filled with content, auto-laid-out, and/or PIN-locked at create time.
get_board — Full structured JSON state of a board: texts (id, x, y, content, color, width, postit, author), strokes (id, points, color, author), images (id, x, y, width, height, dataUrl, thumbDataUrl, author; heavy base64 >8 kB elided to dataUrl:null, tiny images inlined).
get_preview — Compact schematic SVG render of the board (typically a few kB even for dense boards).
add_text — Create a NEW text node, or update an existing one (pass the same `id` to overwrite content/position in place — preferred over creating a duplicate).
add_link — Drop a URL capsule onto the board — rendered as a clickable pill showing the hostname.
add_image — Place a raster or SVG image on the board at (x, y) with explicit width/height in board pixels.
draw_stroke — Draw a freehand stroke on the board.
