Two fixes in one push.
(1) Streaming horizontal-output bug, take three. textContent += chunk
then appendChild(createTextNode(chunk)) both still rendered chunks
horizontally in fox's Firefox tab even though the chunks clearly
contained \\n (node test confirmed; deployed loader hash matched
local; curl-fetched lumbda-c.loader.js carried the line + '\\n' fix).
Whatever the browser was doing with sibling text nodes inside a
<pre> wasn't honoring the embedded newlines.
Switch to one <div class=\"stream-line\"> per logical line. liveBlock.append
walks the incoming chunk byte by byte, every \\n closes the current
pending div and spawns a fresh empty one for the next line. CSS
adds .stream-line { display: block; white-space: pre; } so each
finished line stacks vertically no matter what the parent
white-space rule was doing. Empty lines get a single space so they
take a row instead of collapsing. Reconcile path inside finalize()
compares the joined per-line text to the full output and rebuilds
the div column if they diverge — for the asm-tier fallback we
already had and now also for any future browser/wasm combo where
a flush silently drops a chunk.
Also drops the temporary [c-tier print] console.log debug we added
in the last commit — diagnosis arrived from elsewhere, no point
keeping the spam.
(2) Per-program autosave drafts. scheduleFreeFormSave previously
returned early if the selected program wasn't \"free-form\", so a
user who unlocked the vault, edited the bend-gpu demo, and came
back later found their edits gone — only free-form persisted.
Now drafts live as { [programName]: text } in the vault payload;
every edit, regardless of which radio is selected, debounces a
save into drafts[currentProgram]. unlockVault loads any saved
draft for the current program (and lifts the legacy
top-level freeForm field into drafts['free-form'] so existing
users don't lose their work). loadCurrentDemo shows a saved
draft instead of the ship default whenever one exists; vault bar
stays visible across all programs once the vault is engaged so
the save status note is always reachable.
