Adds Lilac Material Reveal / 紫序·产品微观, an adopted, opt-in style package for product-led imagery: lilac-white studio depth, controlled shell reflections, distinct dry-pigment/fiber materials, purposeful product arrays and element effects with a visible origin or destination.
The guide distills documented product-research and targeted-repair methods without distributing client reference images, brands, private paths or full source prompts. Product geometry, actual material, color and identity remain target-owned; powder effects are conditional rather than a universal style accessory.
Five generation/refinement records cover artist pastels, an electronics array and fiber contact. The refined pastel and wide speaker support two different product mechanisms; the macro supports contact-phase appearance. The initial coarse-powder image remains partial and some coarse material persists after refinement. Initial 3:2 outputs and the later explicit 16:9 prompt suffixes are preserved in the evidence record rather than relabeled as exact-format successes. Four new unbranded example images are included in the README/style guide.
Validation: 255 tests, full local workflow, four-platform target/material preservation, capsule validation, reproducible sent-prompt hashes, published PNG hashes/dimensions, independent visual/package review, PR/main/tag CI, and fresh-process installed-compiler readback. All 176 tracked files and executable modes match the merged commit and ZIP.
The package does not establish physical particle sizes, animation continuity, source-project client approval or universal repeatability. The native-tool handoff note clarifies that standalone compiler parameters must actually be forwarded to prompt-only image tools.
