All five pages — chat (zebra-audio), zebra-audio, how-it-works,
host-your-own, zebra-spaces — now ship with the same dark-mode
infrastructure: pre-paint head script, shared dark CSS block, fixed
top-right theme toggle, and one localStorage key ('zebra-theme-v1')
shared across pages so the user's choice follows them.
Dark IS the default: missing pref reads as dark, only an explicit
'light' opts out. First-time visitors land in dark without a flash.
The shared CSS covers the surfaces every page has (body, links,
buttons, inputs, dots, meter, status, log, hr, footer) so each page
looks intentional in dark without per-page tuning. zebra-spaces keeps
its richer overrides for badges + latency rows + tile metas.
Mobile browsers refuse to autoplay a <video> carrying an unmuted audio
track without a user gesture; the whole element stays paused, so the
video pixels never render either. The phone listener saw a black tile
even with a healthy track flowing.
Start the remote tile muted so it autoplays everywhere; expose an
'unmute audio' button in the meta bar that toggles. The button click
counts as the gesture, so audio kicks in on demand. Local preview never
offers unmute (would feed back into the publisher's own mic).
The SFU does not echo a publisher's stream back, so anyone sharing alone
in a room had no visual confirmation — game iframe stayed up, no tile
appeared. Render a muted local preview keyed by myKeys.pubHex on publish,
remove on unpublish. Subscribe path skips own pubHex to defend against
SFUs that do echo publishers.
Also refreshes integrity stamps on the other web pages (date drift).
- index.html, kernel.html: were missing the viewport meta entirely;
mobile fell back to the default 980px layout and the content was
scaled down. Add the standard 'width=device-width,initial-scale=1'
and centre the body with margin:0 auto so the 640px max-width is
centered instead of left-aligned on wide displays.
- host-your-own.html, how-it-works.html, zebra-audio.html, chat.html:
add a 600px breakpoint that tightens body padding to 1rem, shrinks
the h1 from 3rem to 2.2rem, and lets long URLs / pubkey hashes wrap
via overflow-wrap:anywhere on body prose. .code / .diagram already
use overflow-x:auto so internal scrolling stays bounded to the box,
never pushes the page wider than the viewport.
- chat.html: cap the QR share box's canvas (was a fixed 320px square)
with max-width:100% on phones, so 320px-wide handsets don't overflow.
- zebra-audio.html: the mute button had a fixed 6rem width to keep the
'mute'/'unmute' label from shifting the row; on narrow phones that
width forced wrapping. Drop it back to auto on small viewports.
All pages stamp+verify; the integrity footer hashes in the source
match the served files after `make stamp`.
New page: web/zebra-spaces.html. Extends the rendezvous + WebRTC mesh
model from zebra-audio (1:1) to a room of up to ~8 speakers (host + 2
co-hosts + speakers) with listeners (deferred to v0.2 for SFU fan-out).
Identity: per-browser persistent Ed25519 keypair in localStorage,
plus a per-session UUID for in-room "whose who". Password-vault
backup/restore (PBKDF2 600k + AES-GCM, matches zebra-audio's crypto)
emits a self-contained 'zspc-id-v1|...' blob.
Roles: everyone joins as listener; mods (host + co-hosts) extend
mic-invites that listeners accept/decline; host promotes to co-host;
mods demote and boot. Co-hosts cannot remove the host. Every role
transition is signed by the acting mod's Ed25519 over a canonical
input bound to room_id + epoch, so a compromised relay cannot forge
promotions, only refuse to relay them.
Pairs with cmd/zebra-spaces-signal in proxy.unturf.com.
Nav: zebra-audio and host-your-own cross-link to spaces.
Makefile: stamp target now covers zebra-spaces.html (web/chat.html
and web/how-it-works.html stamps refreshed today as a side effect).
Add web/host-your-own.html and link it from the chat and how-it-works headers
and footers. make stamp now stamps it alongside the other pages. CLAUDE.md:
turn the deploy flow into an explicit push-BOTH-repos reminder (zebra-report
source + www.unturf.com served) and list host-your-own.html as a deployed page.
- chat + zebra-audio: treat ICE 'disconnected' as recoverable (grace
before acting), auto ICE-restart on 'failed'/timeout driven by the
offerer to avoid glare, and auto-rejoin the signaling socket if it
drops mid-call. Superseded-pc guard ignores late events from a
closed connection.
- zebra-audio: input-device dropdown that hot-swaps the mic via
replaceTrack (no renegotiation, mute preserved); refreshes on
devicechange so a plugged-in interface appears mid-call.
Add an integrity footer to chat.html, zebra-audio.html, and how-it-works.html
showing the build date (2026-05-28) and the page's own MD5 + SHA-256. A file
can't hold its own hash, so web/stamp.js (make stamp) computes the hashes with
the two hash fields zeroed, then writes the real values back — self-consistent
and idempotent. To verify a served page: blank the two fields and re-hash;
confirmed it reproduces the stamped value with plain sha256sum.
Standalone blog-style page (matching chunkfive/monospace b&w UX) explaining the
whole solution: amplitude-as-data, the no-copy-paste signaling relay, the
multi-level modem, the Opus->G.711 codec fix and 440 Hz beat, the ACK/outbox
reliability layer, and the Hamming(12,8)+Gray FEC. Linked from chat.html's
header.
