i12bp8 287481453e WiFi plugins: GitHub Profile + DiceBear identicon + tri-state canvas
Worker (cloud-plugins/):
- New plugin 'GitHub Profile': avatar dithered upper-left, display
  name + @handle (with accent star) + word-wrapped bio in the right
  column, followers/repos line, and a 53x7 contribution heatmap
  with an accent palette (red dots for everyday activity, black for
  the rare hottest days). Tuned for 208x112 ESLs and adapts to
  296x128 with a bigger avatar and roomier heatmap.
- Identicon plugin gains DiceBear style selector (pixel-art /
  bottts / lorelei / adventurer / micah / fun-emoji / shapes) on
  top of the original symmetric grid 'local' mode. Both are
  rendered through the new shared image_util pipeline.
- Crypto plugin redesigned: editorial layout with corner brackets,
  bold price headline, white-knockout delta badge with a real
  triangle glyph, currency symbol prefix using the canvas font's
  new euro / pound / yen glyphs, and a stippled accent fill under
  the sparkline.

Canvas:
- setPixel is now last-write-wins across planes, so drawing black
  on top of an accent-filled area produces a clean black pixel
  instead of the muddy plane-conflict the e-paper driver was
  showing previously. Every pixel is therefore exactly one of
  white / black / accent which is what plugin authors intuit.
- New whitePixel + drawTextWhite primitives for knockout text
  (e.g. white labels punched through a coloured badge).
- FONT_EXTRA shipped with the canvas for currency / arrow / shape
  / star / bracket glyphs. Plugins can now write '\u20AC1234' and
  have the euro symbol Just Work.

Image pipeline (new image_util.ts):
- One fetchImageGray() that sniffs PNG vs JPEG, decodes via
  upng-js / jpeg-js, composites alpha over white, and returns a
  tightly-packed grayscale buffer.
- One blitGrayDither() that nearest-neighbour scales the gray
  buffer to a destination rect and serpentine Floyd-Steinberg
  dithers it on the way in. Used by identicon and github.

FAP:
- WiFi BMP writer is now plane-aware: writes the same biPlanes=1,
  biBitCount=2, 3-entry palette layout the rest of the IR TX
  pipeline already understood for web-image-prep BMPs. Tri-colour
  tags now actually receive accent ink from cloud-rendered plugins.
- WiFi run scene un-forces accent: plugins are invoked with the
  tag's actual accent capability and the BMP is opened with the
  matching plane count.
- Run scene now calls bmp_abort on exit so an aborted transfer
  doesn't leak the ~10 KB pixel buffer.
- Plugin manifest cache capped at TT_WIFI_MAX_FAP_PLUGINS=8 (down
  from 16) and the UART RX stream buffer shrunk to 8 KB. Together
  these cut WiFi-flow heap pressure by ~23 KB and fix the OOM
  crashes that occasionally happened when opening WiFi Plugins.
- Broadcast scene auto-transmit fix: enter_callback now filters
  by the >> Transmit << row index, and the cursor defaults to
  row 0 instead of Transmit. Previously a stale OK key-release
  from the prior submenu would land on the Transmit row and
  blast the radio without any user action.
