codec/iip.rs:
- TileCache: (fb_width/16 × fb_height/16) tiles, 8 versions × 256 bytes
each, matching t.java's (8, 16*16) allocation
- TileEntry: versioned read/write at byte offsets within tile data
- decode_iip() handles all 4 modes from the control byte:
- Mode 0/12 (cache-read): tile control bytes select which cached
version of each 16x16 tile to display, no new pixel data on wire
- Mode 4 (write-only): Tight-decoded pixel data written to cache
- Mode 8 (update+read): conditionally writes new data to cache
(bit 7 of control byte = 0 means update), then reads from cache
- Tile control bytes compressed via zlib (varint length) when >= 12
- Sub-types 1-4/8 map to bit-depths 1/2/4/4/8 bpp
- Cache resized on framebuffer resize (ModeChange msg 128)
Wired into session dispatch for encoding 9. Not advertised in default
encoding list — only active if explicitly requested.
codec/tight.rs: made get_or_init() pub for IIP's zlib access.
39 tests passing.

Frontend reconnection:
- WebSocket auto-reconnects with exponential backoff (1s → 30s)
- Re-authenticates with OmniView to get fresh APPLET_ID on reconnect
- Credentials stored in sessionStorage for automatic re-login
- Status bar shows connection state and reconnect countdown
- Disconnect button returns to login screen
Encoding 10 (Raw with tile interleave):
- codec/raw_tile.rs: decodes encoding 10 per ByteColorRFBRenderer.for()
- Flag byte bit 0 selects plain raw vs 16x16 tile-interleaved data
- Deinterleave handles edge tiles smaller than 16x16
- Wired into session dispatch
- 2 unit tests
39 tests passing.

codec/hextile.rs:
- Full Hextile (encoding 5) decoder per ByteColorRFBRenderer.int()
- Handles: Raw tiles, BackgroundSpecified, ForegroundSpecified,
AnySubrects, SubrectsColoured flags
- Background/foreground colors persist across tiles
- 4 unit tests covering all subencoding paths
framebuffer.rs:
- Added fill_rect() for Hextile background/subrect fills
session.rs:
- Wired Hextile encoding 5 into the rect dispatch
examples/record.rs:
- 30-second (configurable) recording session
- Saves 1 PNG per second to out/ directory
- Requests encodings [5, 1, 0] (Hextile, CopyRect, Raw)
- Tested against real OmniView: 10 frames in 10s, no errors
27 tests passing.
