The Gardener's Handbook

Everything in this site is one garden. The mapping is simple:

In a library	In this garden
The shelf	The garden — the bed on the home page
A book	A vegetable — one major topic (a course, a language)
Its pages	Leaves — the individual notes inside

Click a vegetable and you step into its plot: the sidebar shows that topic’s leaves and nothing else, with a path back to the garden at the top.

How it’s organized

src/
├── garden.mjs            ← the registry: one entry per vegetable
└── content/docs/
    ├── japanese/         ← one folder per topic
    │   ├── index.md      ← the topic's home leaf
    │   ├── grammar/
    │   └── vocabulary/
    ├── example-course/
    └── handbook/         ← this page

Planting a new topic

Dig the plot — create src/content/docs/<topic>/ with an index.md home page, then add one Markdown file per note. New leaves appear in the topic’s sidebar automatically.
Put it in the registry — add one entry to src/garden.mjs:
```
{
  slug: 'control-systems',
  label: 'Control Systems',
  veg: 'pumpkin',
  note: 'semester 2',
},
```
That single entry grows the plot in the garden bed, the topic’s own sidebar, and the crest above it. If the topic has sub-folders that deserve labeled groups (like Japanese’s Grammar and Vocabulary), give the entry a sidebar array — copy the one on the japanese entry.
Pick the vegetable — varieties on hand: carrot, daikon, pumpkin, eggplant, tomato, cabbage, turnip, and sprout. They’re all drawn in src/components/Veggie.astro, so a new variety is one more SVG.

Growing good leaves

One idea per leaf. A note called “は vs が” gets reread; “Grammar dump week 3” never does.
Name files for the idea — control-systems/root-locus.md reads better in six months than cs2/lec7.md. Future-you is the most important reader.
Rewrite, don’t transcribe. Notes go down within a day of the lecture, from memory first; the gaps you find are the exam questions you would have missed.

What a leaf can hold

Math ( inline, display blocks, the lot), code with syntax highlighting, callouts, tables, footnotes, and task lists — the sample lecture note shows everything in one place.
