ember: add daily-focus-board skill + address review (rounds 1-3)

Executive-function-friendly daily focus board (self-contained HTML) you run by
talking to Ember. Registers it in the ember plugin (1.1.0) and regenerates the
skills index + marketplace.json.

Review fixes: emoji XSS escaping; keyboard a11y (semantic buttons + aria, plus
up/down move controls); tagc label colors; local-date storage key + recap
date/filename; guarded execCommand and localStorage; confetti animates only
while active and stops on reduce-motion; loopback serve bind + quoted dir;
JSON config injection with '<' escaped; minute rounding; reorder-to-end; clear
stale focus; counter goal guard; and doc corrections (id charset, sample
reference, counter contract, option-b, frontmatter length).

+# Customizing the Daily Focus Board
+
+## Theming
+Colors live in the `:root` CSS block of `assets/board.template.html`
+(`--ember`, `--good`, `--urgent`, backgrounds). The look is warm/dark by default. Tag colors:
+`new` (green), `deadline` (red), `career` (purple) — add your own by copying a `.tag.<name>`
+rule and passing that name as a task's `tagc`.
+
+## v2 — file-backed state (closes the agent loop)
+v1 stores progress in the browser (`localStorage`), which the agent can't read back. To let
+your AI partner *read* your progress (e.g. to write your end-of-day journal) and *write* it
+(e.g. "mark the design doc done" from chat), back the board with a JSON file instead:
+
+- Board writes state to `board-state.json` (via a tiny local endpoint or the File System Access
+  API) instead of localStorage, and reads it on load.
+- The agent reads/writes that same JSON. Now it's a two-way loop: you talk, the board updates,
+  and the agent can summarize the day from the same source of truth.
+
+This is the genuinely *agentic* version — but it needs a small local write path, so it's a
+deliberate upgrade, not the zero-setup v1.
+
+## Optional — the "shared signals" bridge (for multi-agent workshop users)
+The board's momentum notes are the same shape as an agent **progress signal**: a timestamped
+self-report of what got done. If you run a multi-agent setup that emits `.signals/*.json`
+(e.g. one signal per unit of work), you can feed those into the momentum feed so *agent* work
+and *your* work share one timeline — "my personal board and my agent team share one nervous
+system."
+
+Keep this **opt-in**. The board must stand completely alone with zero workshop dependency —
+that's what makes it universal. The bridge is a bonus for advanced users, never a requirement.

+# Neurodivergent-friendly design — principles behind the board
+
+This board is built on well-established **executive-function–friendly** design principles —
+the same patterns ADHD/EF-aware tools use. It is designed to help *everyone* focus, and to be
+genuinely supportive for neurodivergent people. Two ground rules:
+
+- **Don't medicalize or assume.** Never diagnose a user or call it an "ADHD mode." Frame it as
+  focus-friendly design for everyone. Every affordance is optional.
+- **Neurodivergence is heterogeneous.** "Meet one person with ADHD, and you've met one person with
+  ADHD." So these are *configurable supports*, not a prescriptive system.
+
+> Provenance: grounded in established executive-function / ADHD design knowledge from recognized
+> sources — see **Sources** at the end of this doc (CHADD for executive function, Simply
+> Psychology for body doubling, and W3C/MDN for reduced-motion accessibility). These are
+> educational references, not a systematic literature review or clinical guidance.
+
+## Challenge → principle → feature
+
+| Executive-function challenge | Design principle | Feature in the board |
+|---|---|---|
+| **Task initiation** — starting is the wall (activation energy) | shrink the first step; make "next" obvious | agent behavior: offer one tiny first action; **Focus mode** to surface a single task |
+| **Time blindness** — deadlines feel abstract until they're on top of you | make time concrete + visible | live **clock**; gentle **due countdowns** ("2h 10m left"), soft amber when past, never red |
+| **Working memory / object permanence** — out of sight, out of mind | keep it visible + externalized | always-on canvas; the **momentum feed** as external memory of the day |
+| **Overwhelm** — a long list paralyzes | reduce visible load; one thing at a time | **Focus mode** dims all but one; carryover keeps the list short |
+| **Dopamine / reward** — interest- & urgency-driven; needs immediate payoff | instant, visible reward + novelty | progress ring, confetti, momentum feed; **starting counts** (flip to in-progress — the partner can log it in the feed); rotating encouragements |
+| **Perfectionism / shame spiral** — miss one → abandon the whole system | no punishment; partial credit; easy defer | **"not today" carryover** (no overdue-shaming); "in progress" counts; carried items leave the ring math |
+| **Intrusive thoughts** — a stray thought derails focus | frictionless capture, deal with it later | **🧠 brain-dump box** ("park it, keep going") |
+| **Task-switching / transitions** | explicit "what's next" handoff | agent behavior: name ONE next action, offer Focus mode |
+| **Body-doubling** — focus improves with a present partner | be the other-in-the-room | the whole premise: you drive the board *by talking to your AI partner* |
+| **Sensory / motion sensitivity** | calm base, optional stimulation | **reduced-motion toggle** (kills confetti/transitions); honors `prefers-reduced-motion` by default |
+| **Self-regulation / interoception** — reacting before noticing your state | *locate yourself* without judgment first | **above/below-the-line check-in** (from Conscious Leadership); below-the-line quietly softens the partner's suggestions |
+| **Motivation / self-talk** — a bare to-do list is joyless | a kind, chosen intention | **daily mantra** — self-set or 🔄-suggested, keyed to the check-in (grounding when below, momentum when above) |
+| **Prioritization overwhelm** — everything feels equally urgent | separate *important* from *urgent* | **Eisenhower quadrants** (Do first / Schedule / Delegate / Later) + **sort by priority** + a 🧭 plain-language legend |
+| **Agency / ownership** — rigid systems get abandoned | let people shape their own tool | **drag-to-reorder** (or ▲/▼ / keyboard), **editable labels**, **add tasks** live (remove the ones you add) |
+| **Closure / reflection** — days blur together without a marker | end with a gentle, concrete recap | **end-of-day save** — download or copy a Markdown recap; paste it to the partner to journal and plan tomorrow |
+
+## The most important part is behavior, not chrome
+
+The UI affordances matter, but the biggest EF support is **how the partner shows up**: shrink the
+first step, suggest one thing, celebrate starting, never shame an incomplete, offer carryover
+freely, park intrusive thoughts, make time concrete, protect against overload. Those are encoded
+in `SKILL.md` ("Executive-function-friendly behavior"). A pretty board with a shaming, do-everything
+partner would miss the point entirely.

+# Using the Daily Focus Board
+
+A warm, visual board for your day that you run **by talking to your AI partner** (Ember). You set
+the tasks; you keep it current through conversation and a few one-tap controls. This guide covers
+running it in the **GitHub Copilot app** (best experience) and **directly through Ember** anywhere.
+
+## Quick start
+
+Just ask:
+
+> "Make me a focus board for today."
+
+Ember will ask for your handful of tasks (or lift them from what you've already said), generate the
+board, serve it locally, and open it. That's it — you're running your day with a partner.
+
+## Two ways to run it
+
+### A) In the GitHub Copilot app (browser canvas) — recommended
+The app can show a **browser canvas** right next to the chat, so the board lives beside your
+conversation.
+
+1. Ask Ember to make the board. It serves the folder (e.g. `python -m http.server 8790 --bind 127.0.0.1`) and gives
+   you an `http://localhost:…/…html` URL.
+2. Open a **browser canvas** to that URL. The board sits in the side panel; the chat stays on the left.
+3. Talk to Ember as you work; tap the board for quick updates. Progress saves automatically (localStorage).
+
+### B) Directly through Ember (any Copilot session with this skill)
+Same flow, without the side-panel polish:
+
+1. "Make me a focus board for today."
+2. Ember serves it and gives you the URL — open it in your browser.
+3. Drive it by talking + tapping.
+
+> localStorage needs an `http://` origin, so always **serve** the folder rather than double-clicking
+> the file. If you truly can't serve, the file still opens, but progress may not persist.
+
+## The daily loop
+
+**1. Arrive (morning).**
+- **Check in:** tap *below / in-between / above the line* — just noticing how you're arriving, no
+  judgment. (Below the line? Be gentle and shrink the first step.)
+- **Set a mantra:** type today's intention, tap 🔄 for a suggestion, or ask Ember for one.
+- **List ~4–9 tasks.** Keep it a focus board, not a backlog. Mark the one real **anchor** (give it
+  a `due`). Optionally set each task's **priority** (Do first / Schedule / Delegate / Later — tap
+  🧭 for what they mean).
+
+**2. Work (during the day).**
+- Tap a task's pill to move it **to do → in progress → done** (starting counts — celebrate it).
+- **Log momentum notes** ("first draft done") — they build the story of your day.
+- **Focus mode** (🎯) dims everything but one task when the list feels loud.
+- A stray thought? **Park it** in the 🧠 brain-dump box and keep going.
+- Need to capture something new? **➕ add a task** right on the board.
+- Reorder by importance with the **⠿** handle, or tap **⬍ sort by priority**.
+- Rename any tile's **label** inline.
+
+**3. Close (end of day).**
+- Tap **💾 download recap** to keep the day as a Markdown file, or **📋 copy** it.
+- If you copy it, **paste it to Ember** — Ember can journal your day and help you set up tomorrow.
+- Carry unfinished things with **⤳ not today** — that's a healthy choice, not a miss.
+
+## Things to say to Ember
+
+- "I'm below the line today — give me a gentle mantra and one tiny first step."
+- "What should I do next?" → Ember names **one** thing and can turn on Focus mode.
+- "Add 'call the dentist' to the board."
+- "Help me prioritize — what's actually important vs just urgent?"
+- "Here's my end-of-day recap: …" (paste it) → "journal this and plan tomorrow."
+
+## Good to know
+
+- **It's yours and optional.** Every feature is a support, not a requirement. Focus-friendly for
+  everyone; never a diagnosis.
+- **Keep it small.** If it passes ~9 active tasks, the board nudges you — carry a few to tomorrow.
+- **The Schedule quadrant** (important, not urgent) is where the good, non-frantic work lives —
+  protect time for it.
+- **State is per-browser.** The end-of-day recap is how you take your day *out* of the browser.
