+
+=========================
+=== DESIGN PRINCIPLES ===
+=========================
+
+Dead Simple:
+Just put a <script> in the heading and that's it.
+That's why this file even contains the CSS & others' minified libraries
+(This library doesn't even have any dependencies! <3)
+
+Decentralized:
+Nutshell Sections can be re-used across websites & authors!
+
+Backwards Compatible:
+Should work with blogs & writings that *already* exist.
+Uses the standard markup to find sections: <h*>, <p>, etc
+And heck, why not, Wikipedia API integration.
+
+Minimalist:
+don't send me any issues or pull requests for more features
+thx
+
+
+===================
+=== TERMINOLOGY ===
+===================
+
+Nutshell: name of this library
+
+Nutshell Section: a piece of text/html that can be embedded elsewhere.
+  (sometimes just called "Section", or, confusingly, "Nutshell".)
+
+Expandable: a button you can click to get an "expandable explanation"
+  (also called just "Button" or "link". Look, I'm not consistent.)
+
+Bubble: the box that expands below an expandable, containing a Nutshell Section
+
+
+========================================
+=== WHAT NUTSHELL NEEDS TO DO (SPEC) ===
+========================================
+
+1) Convert the top page (or a given element):
+
+  a. Turn :links into expandable buttons
+    <a href="pageURL#Heading">:link text</a>
+    should be converted to an expandable labeled "link text", that when clicked,
+    expands a bubble with the section found inside the purified HTML.
+
+    Ways to get a section:
+    * pageURL – Get whole article
+    * By heading:
+        #Heading – Find heading whose text matches,
+          get everything up to next heading or break.
+        #Heading&cut=[integer] – Same, but skip last [cut] elements
+    * By paragraph text:
+        #start=[text] – Get FIRST paragraph containing that text
+        #start=[text]&length=[integer] – same, w/ followup <p>
+        #start=[text]&end=[text] – same, til <p> that matches end.
+    * Add before & after:
+        &before=[markdown]&after=[markdown] – add html like pre-req's, commentary.
+
+  b. Give <h*> headings two reveal-on-hover buttons:
+    one for permalink, one to embed that Nutshell
+
+  c. A modal dialogue to let readers embed Nutshells
+
+  [NEW]
+  d. A "close all Nutshells" button when more than one Expandable is open.
+
+  By default, do all this on DOMContentLoaded (no need for images loaded first)
+
+2) When an Expandable is opened, it should...
+
+  a. Get HTML of the source page
+    If already cached, use that.
+    If not,
+      Get raw HTML:
+        - If *this* page, easy peasy.
+        - If remote page, try fetch.
+          If CORS fails, use iframe & postMessage to get the HTML
+        - If it's Wikipedia, use their API.
+      Process it:
+        - DOMPurify it: no styles, no scripts, iframes allowed but sandboxed
+        - Convert all links to absolute, and open in new tab
+      Cache it!
+
+  b. Make an element to contain the Section
+
+    Get the Section's HTML from "#Heading", &before, &after, &start, &end, etc
+    Do very forgiving search: case-insensitive, don't care about punctuation.
+    Convert :links inside it to Nutshell Expandables, too (yay, recursion!)
+
+  c. Put Section element below "expandable" (after punctuation) in a Bubble:
+    - bubble head: link to source (if remote), embed button
+    - bubble foot: close button
