郭浩 f492caeb8b v0.15: Live Photo 生产规则 — 平台限制、拼图版式、长视频处理、发布提醒、可见文案规则
新增 Live Photo 正式能力:单视频、二宫格、三宫格、四宫格、三连拼图、
长视频低成本诊断。增加 references/live-photo-production.md 生产规范、
scripts/ 工具链(contact sheet / .pvt 打包 / Apple metadata)、
validator R8 visual bounds + R9 title gap、文档约束测试。

由 Codex 完成主体实现。

* Rules implemented:
* R1 overflow scrollHeight > clientHeight on the poster
* R2 footer collision .foot is position:absolute AND content above reaches into its band
* R3 swiss bold display .h-xl / .h-hero / .h-statement / .num-mega with computed weight >= 600
* R4 min readable font body/lead/caption/label/meta below the mobile-safe floor
* R5 4-band density on 3:4 boards: <75% filled OR any under-filled band > 216px
* R6 h-xl hard cap display title lines/chars exceed the per-board cap
* R7 figure margin drift browser-default <figure> margin offsets media alignment
* R8 visual bounds measured top/bottom blank space and visual overflow
* R9 title gap display title touches the next content block
