- .cc-shape-header and .cc-shape-toolbar button were missing pointer-events:all,
causing toolbar buttons to be unclickable inside tldraw canvas
- Replace color:'white' on lock indicator with var(--cc-text-inverse)
Commit 669a661 had a stale staged deletion of cc-design-system.css and
reverted three other CSS-variable files. This commit restores them to
the state from cd37771 (adopt --cc-* CSS variable system).
Bugs fixed:
- 'cc-teacher-timetable-node' missing from NODE_TYPE_THEMES caused
Cannot read properties of undefined (reading 'headerColor') crash
when clicking My Timetable
- 'cc-journal-node' and 'cc-planner-node' had no shape utils registered,
causing 'No shape util found for type' error on Journal/Planner click
- Added null safety (?? fallback) to getNodeTheme to prevent future crashes
from any other unmapped type
- Removed AcademicWeek from canExpand exclusion so weeks can be expanded
to show individual academic days
Added:
- CCJournalNodeShapeUtil and CCPlannerNodeShapeUtil (stub shapes)
- CCJournalNodeProps and CCPlannerNodeProps types
- Journal/Planner added to CCNodeTypes, ccGraphShapeProps, NODE_TYPE_THEMES
- 'cc-department-structure-node' mapping added to NODE_TYPE_THEMES

navigationStore: rewritten off Neo4j db names — Supabase whiteboard_rooms table,
setAuthInfo(token, userId) pattern, auto-creates default room per context on first use
snapshotService: rewritten to Supabase Storage REST (/storage/v1/object/authenticated/cc.users/…),
setAccessToken() instance method, static methods take accessToken not dbName
AuthContext/NeoUserContext: auth injected into nav store, no Neo4j db names required
singlePlayerPage: loadNodeData no longer calls Neo4j; snapshot wired via accessToken
navigation types: NeoGraphNode updated for Supabase-backed tree structure
transcriptionStore/Service: getSession() removed, accessToken via AuthContext
LLMConfigModal: auth context wiring fixes
GraphNavigator/GraphSidebar: updated nav components

Root causes of disconnection and slow transcription:
- AudioWorklet was firing every 128 native samples (~48 kHz), sending
~375 tiny WebSocket messages/sec. Server flooded with tiny frames
during silence → keepalive ping timed out → connection dropped.
- JS resampling 48 kHz → 16 kHz added CPU overhead on every chunk.
- Audio started on ws.onopen before server sent SERVER_READY, so early
frames were dropped.
Fixes:
- audioWorklet.js: accumulate 4096 samples before posting (256 ms/chunk
at 16 kHz, ~4 messages/sec), transfer ArrayBuffer zero-copy.
- transcriptionService: AudioContext({ sampleRate: 16000 }) — browser
handles native resampling, no JS resampling needed. Remove
resampleTo16kHZ entirely.
- Wait for SERVER_READY message before calling setupAudioProcessing().
- Send 'END_OF_AUDIO' string on stop so server can finalise last segment.

- transcriptionService: track finalizedSegmentCount so only newly-final
segments are emitted per WS message (was re-processing full array each
time, causing the live segment to freeze in the completed list)
- transcriptionStore: saveSegment isFinal branch now appends the passed
text directly instead of currentSegment (currentSegment was stale
relative to the incoming final)
- CCTranscriptionPanel: record button colour changed from var(--color-text)
to explicit #2563eb so it is visible in dark mode; completed segment
backgrounds changed from hardcoded #fff to var(--color-muted) so text
is readable in both themes; keyword Add button gets same blue fix

The old startTranscription() called enumerateDevices() first to find a
device ID, then getUserMedia. Without microphone permission, enumerateDevices()
returns devices with deviceId="" (empty string, falsy). This caused the
!this.selectedDeviceId check to bail out early, never calling getUserMedia,
never prompting the user for mic permission, and never creating the WebSocket.
Result: user clicks Start Recording → isRecording=true → button changes to
Stop Recording → but no mic prompt, no WebSocket, no transcription.
Fix: call getUserMedia directly (with optional echoCancellation/noiseSuppression
if no device pre-selected). getUserMedia triggers the browser permission prompt
automatically. Device selection is still honoured via exact deviceId constraint
when one has been explicitly chosen.

- Connect transcriptionStore to Supabase (start/stop session, save segments)
- Add CanvasEventLogger for silent TLDraw activity tracking
- Add Sessions tab to CCTranscriptionPanel with past sessions list
- Auto-detect timetable context on panel mount
- Flush canvas events to API every 5 seconds during recording
