As an instructor I want to photograph a gym whiteboard and have it create a gruppetime template so I don't have to enter exercises manually

[ChristopherRotnes]

Summary

Instructors currently photograph a whiteboard to log a session, but the OCR flow lands in the MuscleMap confirm step and does not offer to save the result as a reusable gruppetime template. A separate camera entry point in the Sett-sammen tab should let instructors capture a whiteboard, review the parsed exercise list, and save it directly as a named template in the library — without logging an actual session.

Priority

Medium

UI spec (Carbon g100)

• Entry point: «Knips tavla» featured card in SetSammen landing (below the two existing ActionCards), using the Camera Carbon icon; same two-color treatment as the existing cards
• Flow:
  1. Camera/file picker opens (same <input type="file" accept="image/*" capture="environment"> pattern as MuscleMap)
  2. Image compressed via existing compressImage util — same 5 MB base64 limit
  3. Synchronous Claude Vision call via /api/claude (same proxy, no jobId, no polling)
  4. Result lands in a review step: editable exercise list (same ExerciseRow pattern), template name TextInput at the top, live BodyPanel coverage preview
  5. «Lagre som mal» Button kind="primary" saves via replaceTemplateExercises + saveTemplate; navigates to GruppetimePicker on success
  6. «Avbryt» discards and returns to SetSammen landing
• Error states: InlineNotification for compression failure, Claude error, or save failure — same patterns as MuscleMap upload step
• No session is created — this flow is template-only

Data model

No schema changes. Uses existing session_templates + session_template_exercises tables and existing replaceTemplateExercises / saveTemplate db.js functions.

The analyze prompt (ANALYZE_PROMPT in prompts.js) is reused as-is — output shape is identical to the session log flow.

Acceptance criteria

• «Knips tavla» entry point visible on SetSammen landing
• Camera/file picker opens on tap; image compressed to within Anthropic 5 MB base64 limit
• Claude Vision call is synchronous — no polling, no jobId
• Parsed exercises shown in editable review step with live body map
• Template name field required before save is enabled
• Saved template appears in GruppetimePicker immediately after save
• No session row is created in sessions table
• Error states handled with InlineNotification (compression, Claude, save)
• Flow works on iPhone Safari (HEIF image, iOS canvas quirks — see known pitfall fix: surface API errors, compress HEIF images, fix sessions vanished, fix slow load #173)

Out of scope

• Multi-image capture in one template
• Editing the template after creation (use GruppetimeEditor for that)
• Session logging from this flow

[ChristopherRotnes]

Closing as not a priority. The flow largely duplicates the existing session capture path with a different save destination — can be revisited if demand arises.
