table lesson 00
undo.cafe
A quiet tutorial table for reversing mistakes without pretending they never happened.

Steam curls backward before the page does.

History is not a wall. It is a branching table sketch.
history stack coaster
Lift one state. The earlier version is still warm underneath.
stamp
restored fresh receipt placed over the smudgeSpill / the mistake
concept 01
The line shakes before it teaches.
A mistaken command is not deleted from the lesson. It trembles in graphite so the recovery path can be seen.
incorrect state
rename final.html final-final.html
forget original route
correction note
pause the pour
The first undo is attention: hold the current state still enough to compare it with the one before.

concept 02
History is stacked paper, not a verdict.
Each receipt keeps a small timestamp. Read downward to understand the spill; lift upward to recover the calm version.
prior states
hover the coasters to reveal the previous cup-ring.
Undo / rollback
keyboard glyph
CtrlZ
Press the quiet ritual: not panic, just a measured loop backward.
concept 03
The card inhales, then the receipt lands.
Undo gathers the error inward. The fresh state is placed on top, visible as a new paper layer rather than a magical disappearance.
rollback demonstration
button: delete all drafts
button: restore selected draft
Redo / try again
concept 04
Redo is not stubbornness. It is a second pour with steadier hands.
After rollback, the forward path can be redrawn. Redo keeps the useful intention and leaves the spill behind.
redrawn path
The second curve is thinner, calmer, and easier to follow.

table lesson complete
Recovery leaves a cleaner table, not a spotless myth.
Practice by noticing the mark, tracing the stack, rolling back gently, and trying again with the receipt still in view.
