@@ -369,6 +372,41 @@ Reach for it when the spike's real open question is which of several directions
 build. Once a direction is settled, the deliverable is the two artifacts above, and both
 ship with the ticket.
 
+## The plan page (`plan.html`)
+
+`plan.md` is the plan. `plan.html` is the same plan as a page, saved beside it, so Gib
+reads the plan in a browser before approving it instead of scrolling a markdown file. It
+opens from `file://`, ticks acceptance criteria and steps as he reviews them, and shows
+the mocks in place. It is the review artifact, and it exists to be opened.
+
+- **Fill the template.** Copy `~/.agents/skills/ticket/templates/plan.html` to
+  `<target-dir>/plan.html` and fill every slot its header comment lists, in the order
+  `plan.md` carries them: the same criteria, the same open questions, the same Approach,
+  the same steps with the same `(mock)` and `(deliverable)` marks as badges, the same
+  risks, the same test plan. Fill the slots only. The CSS and script ship as they are, so
+  every plan page looks and behaves the same. Done when a reader of either file learns
+  nothing the other omits.
+- **Mocks, when a step changes what a user sees.** A new screen, a changed layout, a new
+  control, or copy a user reads means the page keeps its Mocks section: one artboard per
+  screen state the plan introduces, drawn in plain HTML and CSS inside its own
+  `<template>`, with the app's real navigation and density around it rather than a
+  wireframe of boxes. When the direction is Gib's call, draw each candidate as its own
+  artboard (Option A, Option B) and name the choice in Open questions, pointing at the
+  artboards. When the direction is settled, one artboard per screen. Each artboard's
+  `data-note` states what it shows that the implementation will not do. This is how the
+  house rule about several static mocks before touching real components is satisfied
+  inside the ticket flow, so no separate mock server is needed. When no step changes
+  what a user sees, delete the Mocks section and its nav link.
+- **Open it.** After saving, run `xdg-open <target-dir>/plan.html` so it lands in the
+  browser, and give both paths in the Phase 1 wrap-up.
+- **`plan.md` stays the source of truth.** When Phase 0 routes to rewriting the plan,
+  rewrite `plan.html` with it. Phase 2 checks steps off in `plan.md` only. The page is a
+  snapshot for the review and is left alone once the plan is approved.
+- **Relation to spike mocks.** The plan page's artboards are design intent drawn before
+  any code exists. A deliverable's polished `mocks/` (see Mocks and datamodel changes)
+  can start from the approved artboard, and the built screens are still screenshotted
+  for real.
