Fragment shortcode + session log template (garden#6)

New shortcode: {{< fragment type="dialogue" label="..." >}}...{{< /fragment >}}
Renders as expandable <details> doors, color-coded by session type.
Full CSS for fragments in garden.css: dot, door label, session ID,
tinted background on open.

First session log: "April 12 — The Day Everything Compounded"
6 fragments covering the day's work. The context.html format
made reusable as a Hugo writing pattern.
