Yogesh OjhaandClaude Opus 5 2cb8d73280 style: strip explanatory comments across the codebase
The comment rule in CLAUDE.md is one line maximum, never narration: no
multi-line blocks, no module-header explainers, no sentences that explain or
justify the code to the reader. The tree had drifted a long way from it, and
most of the drift is mine.

Removed:
  232  lines of multi-line comment blocks
  203  single-line comments that argued instead of stating
  154  comments joined by so/because/otherwise/rather-than
  143  narrating comments in the frontend
  112  test docstrings (the test name already says what it asserts)
   25  test module docstrings and 25 decorative section dividers

Collapsed:
  324  multi-line docstrings to one factual line
  271  one-line docstrings that had a justifying clause bolted on

Kept: functional directives, section dividers, short field labels, alembic
revision headers, and the eight FastAPI route docstrings that render in /docs.
Where a fact was load-bearing it is in CLAUDE.md, which is where it belongs.

284 python tests and 34 frontend tests pass, ruff and ruff-format clean across
ten packages, svelte-check 0 errors, prettier and eslint clean, app.main imports.
