neighbor-sum-avoidance (T2-T6):
- Start button now reads just "Start" (no mode suffix).
- Available numbers and shuffled preview arrangements render pre-start
so the arena isn't empty while the user is still deciding.
- Mode switch + count slider stay mounted once active; they're just
disabled, so starting no longer causes a layout jump.
- Guided-mode instructions expanded to call out light grey edges, red
violation arcs, and the green valid-neighbor line explicitly.
- Draggable numbers honor isActive for the draggable attribute and
onDragStart, showing opacity-60 + cursor-not-allowed when locked.
computing-pi (new interactive under Miscellany):
- N parallel first-passage simulations: toss until heads > tails,
record the fraction. Average × 4 converges to π.
- Header row: runs slider | live average × 4 | Start/Reset.
- Tile grid uses a mask-gradient marquee so long sequences scroll
their tail while staying readable.
- Click any tile once all runs complete to see the full toss sequence
in a Dialog.
- Safety cap of 1000 tosses per run (first-passage time has infinite
expectation, so without the cap a pathological run could block).
- Registered in interactives.ts + InteractiveRenderer + the parallel
interactive-components map. Filled in three-bank-accounts in the
latter while there, since it was missing.
admin-data.json updated to mark T2-T6 done with remarks, remove the
implemented Computing Pi idea, and add an implementation note.
Server side: writeData() now takes a message, and each action in the
POST handler computes its own — e.g. "admin: add idea "Title"", "admin:
clear note on slug". For setTodos (which ships the whole blob), diff
old vs new per slug to produce messages like "neighbor-sum-avoidance:
add T6" or "mark T1 done, add T5".
Client side: syncFromServer() falls back to the bundled admin-data.json
when /api/admin is unreachable, so the admin panel reflects committed
state under `astro dev` (which doesn't run Netlify Functions).

Show the circle arena before the user clicks Start (greyed via
opacity-60 pointer-events-none), and guard drag/drop/click handlers on
isActive. Clicking Start enables interactions and kicks off the timer
as before. Also resync slot count with the Numbers slider while idle.
Marks T1 done.

The form.tsx UI component imported react-hook-form and
@radix-ui/react-slot which aren't installed. Nothing uses
this component — removing it cleans up the dev server output.

Remove Astro adapter (causes esbuild bundling errors on Netlify)
and use a pure static build + standalone Netlify Function instead.
- Removed @astrojs/netlify adapter — site builds as fully static
- Created netlify/functions/admin.mts as a standalone Netlify Function
- Function handles all admin API operations via GitHub API
- Removed src/pages/api/admin.ts (Astro SSR route)
- Local dev: admin syncs to localStorage (server sync fails silently)

- Swap @astrojs/node for @astrojs/netlify adapter
- Admin API reads/writes admin-data.json via GitHub API in production
- Status changes (commitStatus) and deletes commit directly to repo
- Env vars: ADMIN_PASSWORD, GITHUB_TOKEN
- Local dev falls back to filesystem (no env vars needed)
