Tall black-and-cream linocut print with no readable text: a crowded European Christmas market lane at night, snow-covered stalls, string lights, falling snow, and a Gothic cathedral spire, high-contrast hand-carved hatching. 来源：https://prompts.chat/prompts/cmwadzirw0001l50884k5a1sy
A traditional black-and-cream linocut print of a crowded European Christmas market at night, tall portrait 3:4. A narrow cobblestone lane runs between wooden market stalls with peaked snow-covered roofs; a dense crowd in heavy winter coats and hats walks between the stalls. In the background a tall ornate Gothic cathedral spire rises into a solid black sky filled with falling cream snow dots. Three strings of round festival lights swoop across the upper third with soft white halos. Left stall shows jars and hanging ornaments; right stall sends a plume of steam from a tray of roasted chestnuts. High-contrast hand-carved hatching, block-print woodgrain feel, ink-black and cream paper only, lively winter-night mood. No readable shop names, no logos, no watermarks, no modern brand marks.

Flags short trips. Includes a stdlib Python planner with --self-test. 来源：https://prompts.chat/prompts/cmvhsbqp7000nle08uvst5ots

Plans a day hike leg by leg. Estimates time with Naismith's rule and Langmuir's descent corrections, adjusted for terrain, fitness, pack weight and breaks, gives clock times for each leg, checks the finish against sunset and the latest safe start, and works out water to carry between refills and snacks to pack. Flags after-dark finishes, long dry stretches and hard terrain late in the day. Includes a stdlib Python planner with --self-test. 来源：https://prompts.chat/prompts/cmvoxmzkk0001jk08elffowri
Splits a CSV ledger of shared costs for a trip, flat or event - equal, shares, exact, percent and itemized bills with tax/tip pro rata, 'all except' exclusions, several payers, refunds, repayments and multiple currencies at agreed rates - in cents, then finds the provably fewest settle-up transfers (exact zero-sum subgroup search). Returns balances, a per-person audit and a chat message. Includes a stdlib Python planner with --self-test. 来源：https://prompts.chat/prompts/cmvw36uun0001jw07xu4uz2md
