T9: The center avg display is now a <button>. Clicking it toggles
between showing avg × 4 (with 'π ≈ 3.1416' reference) and showing
plain avg (with 'π/4 ≈ 0.7854'). Label flips accordingly. Subtle
background hover wash to hint at interactivity.
T10: Added a second instruction line below 'Click on any of the
completed runs to view the full sequence.' calling out the avg
toggle. Both lines sit in a shared centered text-muted-foreground
container with small vertical gap.
T5: Added a centered <footer> below the Card crediting Jim Propp's
paper, the LinkedIn post, and Arghya Dutta — markdown links rendered
as anchor tags with target=_blank rel=noopener noreferrer.
T6: Reset button shows a mono ({stoppedCount}/{n}) suffix while any
run is still active; the suffix disappears once all runs stop.
T7: Tile clickability is now per-run (run.stopped) instead of gated
on allStopped. Since stopped runs are immutable, the detail Dialog
stays accurate while unrelated tiles keep ticking.
T8: Added a small instruction note between the header and the tile
grid: 'Click on any of the completed runs to view the full sequence.'
The old 'All runs complete' banner is reduced to the discarded-runs
callout only.
Small black dot on the H/T row at left: (H / total) * 100%. The
midpoint corresponds to H = T, so the dot crosses the middle exactly
when a run hits the stopping condition (H > T). Discarded runs end
the simulation with their dot still left of center.
T1: MAX_TOSSES_PER_RUN is now 5000.
T2: Tiles in progress past 500 tosses wear a progressively darker
amber wash (units of 500, up to 9 levels). Completed runs stay green.
T3: Runs that hit the cap are now flagged discarded. They carry a red
wash and an italic 'discarded' footer, are excluded from avg × 4, and
the summary / detail dialog note how many were dropped.
T4: Added a grey H/T header strip to each tile showing the running
heads count on the left and tails count on the right.
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.
Agents processing todos/ideas from admin-data.json should mirror them
as cards on the author's Fizzy board. Slug → tag, progress → Review
column, staging branch link in the card description. PAT is read
from FIZZY_PAT env var; never hardcoded.
- Replace literal admin password with a pointer to where it lives and
the ADMIN_PASSWORD env var override.
- Add a design section covering the shadcn-first approach, OKLCH
design tokens, mandatory dark-mode pairing, typography pairing
(Castoro serif display + Imprima/Geist sans), radius scale, motion
libraries and reduced-motion handling, and the tab/card/alert
patterns that published interactives tend to share.
Documents the three-place registration dance for interactives
(interactives.ts, InteractiveRenderer.tsx, interactive-components.ts),
the admin function's text-editing of source files, routing, and
Netlify-specific build workarounds.
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)

Vite/Rollup generates chunk names with !~{} characters that cause
esbuild syntax errors on Netlify's build system. Added sanitizeFileName
to replace special characters with underscores.
