Swap published columns for 24 entries from random.md

Retract the seven published columns into drafts/ and promote the 24 per-date
entries split out of Notes/random.md. Bodies are verbatim; titles, subjects
and slugs are new.

Make publication a matter of location. Notes/Notes.11tydata.js gives anything
under Notes/ permalink: false unless tagged `column`; drafts/drafts.11tydata.js
renders drafts at their real permalink under `yarn dev` and excludes them from
collections entirely in a build, so no template can surface one. Publishing is
now `git mv drafts/<file> columns/`, and moving it back retracts it.

Untagged notes were previously rendered into _site/ and deployed — including
Notes/random.md, which was live at /Notes/random/.

+## Prompt
+- The kernel of an idea
+- It's generally recommended to plant a seed first
+    - something you can return to over time
+    - reference other ideas you come across
+    - develop and refine
+
+## Questions
+- Questions give structure to your work
+- Even implicit ones - the unsaid queries that motivate the composition of the piece
+    - what's included, and when?
+    - as important: what's left out?
+    - make everything a deliberate choice
+- Why write, if not to test an idea against your own specific qualities? To see if there's a reaction, some expansiveness or contraction.
+- They provide the substrate to thought, and the nourishment, encouraging the frontier to expand
+
+## Rough Notes
+- The heap
+- The outlet for stream of consciousness thinking
+    - See what associations bubble up to the surface
+    - See what resonates, what clusters, the affinities that form
+- The warmup
+
+## Quotes
+- For the sake of having an opinion, I say it's better to rearticulate someone's idea in your own words, to digest it with your own acuity, than to simply reexpress the idea as a quote.
+- Other than stating something factually: at such a time, such a thing was said
+- Refernce it, so motivated readers can connect with more writing that may expand on the idea.
+- But don't just repeat the statement verbatim. Connect with the idea, exppress it in your own way for your own audience. Make it available.
