Replaces the terse graph-theory equivalence line with an invitation to
experiment with the editor — mentions picking a premade motif or
making / saving / sharing your own, and flags that disjoint designs
aren't supported yet.

Single defer'd <script> in BaseHead so it lands on every page
(homepage, theme pages, full interactives, embeds, admin, blog).
is:inline keeps Astro from processing it.

Adds a centered footer under the dead-end banner thanking Priyam and
linking to the Wikipedia page, the rocksea tutorial, the IITGN
course, Guddi Crafts, and the Instagram handle.

Lifted the legal-stitches check into a deadEnd flag shared by the
banner and both fabric panels. When the user runs out of legal moves
on the active side, both SVG canvases fade to bg-muted (a light grey)
with a smooth transition — a passive cue to match the existing amber
banner.

isNeighbor now also accepts unit-diagonal steps, and the editor adds
two diagonals per cell on top of the orthogonal edges. Diagonal hit
areas are rendered underneath the orthogonal ones so edge clicks
still prefer the straight segment and centre-of-cell clicks hit the
diagonal. Uploaded motif files with diagonal segments pass
validation.

The active-side current vertex is red (primary) again; the green is
reserved for the go-indicators. A ring pulses briefly (SMIL animate
on r + opacity, keyed on side+vertex) each time the cursor lands,
to draw the eye — browsers won't let us move the OS mouse pointer.

UI cleanups:
- MiniPreview fits every motif into a 60×60 box (Snowflake no longer
overshoots its card).
- Reel replaces the native overflow scrollbar with a scroll container
plus left/right chevron buttons and edge fades that appear only when
there is more content in that direction.
- Legal-next vertex markers are green instead of red; the current
vertex renders green on the active side and muted grey on the
inactive side (making the side-flip obvious without a jump).
Thread colours:
- Each fabric panel now has an extra swatch opening the native colour
picker, so the user can dial in any thread colour beyond the five
presets. The swatch shows a conic rainbow and highlights when the
current colour isn't one of the presets.
Editor:
- Validation simplified to connectivity only (the alternating Eulerian
tour on the doubled graph exists for every connected base graph, so
odd-degree vertices don't actually block solvability — the extra
warning was misleading).
- Download button exports the current motif as a small JSON file
({kind: "kasuti-pattern", version: 1, edges: [...]}); Upload reads
one back in, validates structure (orthogonal unit segments only,
fits in the editor grid), and loads it centered for editing.

Adds Rose, Totem, Figurine, and Snowflake to the motif reel — inspired
by patterns 1/2/4 on the reference sketch and the red snowflake
sample. Each is an Eulerian graph so an alternating tour exists
(36/24/34/52 stitches respectively).
Appends a "+ Make your own" tile at the end of the reel that opens a
dialog-based pattern editor: click between dots on a 14×14 grid to
toggle stitch segments. The editor reports connectivity and Eulerian
status live and only enables "Use this motif" once the pattern is
connected. The saved custom pattern is centered into the main grid
and selected immediately.

Trace traditional Kasuti embroidery motifs so the design appears
identical on both sides of the fabric. Two side-by-side 20×20 SVG
fabrics (front/back); the active side flips after every stitch, and
only legal unvisited pattern edges from the current vertex are
clickable. Seven Eulerian motifs in the top reel (Square → Temple),
per-side thread colour pickers (default black on front, red on back),
undo / reset, completion detection + canvas-confetti.
Implemented from the idea in admin-data.json; idea removed and
replaced with a note on the slug.

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).
