Mascot Style Guide¶
This page shows all Cress admonition styles for reference and testing. Use it to verify that images load, colors render correctly, and text wraps cleanly around the floated mascot image at various viewport widths.
Neutral¶
A Note from Cress
This is the neutral style — used for general sidebars, introductions, or
any note that doesn't call for a specific emotional tone. Think of it as
Cress just hanging out and offering context.
Welcome¶
Welcome, Hydro-Explorer!
Let's grow something amazing! In this chapter we'll dive into the science
behind [topic]. By the end you'll understand exactly what's happening at
the root level — and why it matters for every system you'll ever build.
Thinking¶
Key Insight
Notice that pH affects every nutrient differently. At pH 6.0, iron is
readily available; at pH 7.0, it's almost completely locked out. That
single variable controls the whole nutrient availability picture — and
it's why growers obsess over that 5.5–6.5 sweet spot.
Tip¶
Cress's Tip
Always calibrate your pH meter in fresh buffer solution before each
measurement session. A dirty or dried-out probe can read off by a full
pH unit — and that's a nutrient disaster waiting to happen!
Warning¶
Watch Out!
Never mix concentrated calcium nitrate and magnesium sulfate together
directly — they'll form a chalky precipitate that blocks your drip lines
and locks nutrients out of solution. Always dilute each salt separately
in water first, then combine.
Encouraging¶
You've Got This!
Nutrient chemistry can feel overwhelming at first — there are 17 essential
elements, and they all interact. Root for it! Every experienced grower
started right here, staring at the same Mulder chart. Take it one nutrient
group at a time.
Celebration¶
Fantastic Work!
You've completed the chapter — that's nutrient-level cool! You now
understand how plants absorb water and minerals, why oxygen at the root
zone is critical, and how to distinguish passive from active transport.
That's the foundation everything else builds on.
Image Border Debug View¶
The section below adds a red border around each image to verify trim quality. Remove this section once images are finalized.
Red border should hug the visible frog content with minimal transparent
padding. If there is significant empty space inside the red border, run
the trim script on this image.
