Please revise the Northbank Museum presentation from this conversation. Keep the original version available and create a clearly labelled revised version. Correct the rendered slides themselves, not just a summary in chat.

The first PDF changed Week 2 attendance from 55 to 52 and Week 3 from 50 to 63. Its capacity-80 reference line was below several bars even though every attendance count is below 80. On the financial slides, the $840 contribution bar was taller than the $920 cost bar. Several requested totals and cost components were missing.

Use exactly six English slides, including the cover, in this order:
1. Northbank Museum: September 2026 late-opening pilot. State that these are fictional test data and the museum manager must decide whether to extend the pilot for another month.
2. Four-week source table: Week 1 = 40 of 80, 50%; Week 2 = 55 of 80, 68.75%; Week 3 = 50 of 80, 62.5%; Week 4 = 75 of 80, 93.75%. Total = 220 visits out of 320 available places, 68.75% overall. Do not describe visits as unique people.
3. Attendance chart using exactly 40, 55, 50 and 75 in that order. Use a labelled zero baseline and linear scale. Put the 80-person capacity line above all four bars. The Week 3 bar must be shorter than Week 2. Labels and bar geometry must agree.
4. Inspectable financial calculation: revenue 220 x $8 = $1,760; staffing 4 x $120 = $480; materials 220 x $2 = $440; listed costs $480 + $440 = $920; contribution $1,760 - $920 = $840. Call it contribution after listed costs, not net profit. Use a clear table instead of a financial bar chart to avoid misleading proportions.
5. Limits: marketing and other omitted costs and visitor satisfaction are unknown; no comparison group, proven cause or reliable forecast. Week 3 fell from 55 to 50. The later increase to 75 does not establish why it happened or that it will continue. Invent no facts, quotes or external sources.
6. Conditional recommendation to the museum manager: verify marketing and other omitted costs and collect visitor satisfaction before approving an extension. Do not give unconditional approval or change the audience to a board.

Keep all six slides readable, in a true 16:9 frame, with charcoal text, warm ivory background and a burnt-orange accent. Preserve all numbers and financial limitations. Check every rendered slide against these requirements before returning it.

Provide the actual available downloadable file. If a native editable PowerPoint file is genuinely available, include it. Otherwise, state the actual format and its editing limits. Do not publish a public share link. Please proceed with this revision; if your workflow requires an outline confirmation, show the outline first.
