[M2-S10] Chair sprite sheets: sweeps, up attack, slam, guard #81

User story

As a player, I want the chair attacks to read clearly at 80 px, so that I know what each button does.

Acceptance criteria

• chair-side: sweep A 8 · sweep B 8 · recoil 2
• chair-overhead: up attack 6 · down slam 7 · air pogo 4
• chair-block: guard up 4 · hold 3 · impact 4 · break 4
• One smear frame on each fast swing

Design and references

Made with scripts/make_boards.py from art/sprites/boards.json: the approved hero sheet first, the pose or object photos next, the style master last; magenta key, crushed to 96 colours. See 09 – Art pipeline (including Smooth, not rubbery) and 06 – Visual direction. No text in the art, the face never visible. Chair photos are split by file name into block, overhead and side. Frame lists: 07.

Dependencies

Suggested owner: Alexander (pipeline, art, scenes, deploy).

Verification

Review page under art/sprites/ shows the sheet and a looping preview at game size (hero 80 px). The Design review field on the board is set to Approved by Alexander before the sheet is exported.
