Enter fullscreen so the board, anchors, timeline, and thumb controls remain inside the safe area.
Move each seed onto the flower with the same glyph at the end of a four-beat breath.
Drag from a glowing border anchor through adjacent cells to the other anchor. Mouse drag works; keyboard users activate anchors and cells with Enter or Space.
Every old current replays. Combined arrows can move diagonally. Scrub Start–4 before Commit; coral previews name failure, and Retry restores the exact garden.
Draw a current between the enabled border anchors. Each cell receives the arrow leading to the next cell. At Commit, every current—old and new—moves every active seed for four exact beats.
Opposites cancel, reinforcement still moves one cell, and perpendicular arrows combine into a diagonal. Seeds move simultaneously. Edge, thorn, and same-cell or swap collisions fail visibly.
This sandbox proves the signature two-current solution. It is not the production campaign or production UI.
Both glyphs bloomed.
