Hover engraving
A block's identity on a 420 ms dwell: Surface(tip) beside its first line with the kind and details in Label(engraved), derived tags as Chip(tag) and the recognizer's status with a Led.
Use it for
- Telling what a block is and where it came from, without a card: LOG · 07:40 · SLEEP 6 H · ALSO TIRED, TASK · TOMORROW 16:00 · #POSTER · RECOGNIZER ✓, LUNCH? 0.71, NOT SENT · LOOKS LIKE A SECRET.
Don't use it for
- Anything a person must read to act. The engraving repeats or names what the block already shows (the label role never carries information alone).
- Controls. It is not interactive and ignores the pointer.
- Tooltips on chrome. Those are tooltips; the provenance of a single cue is the provenance tooltip.
