/* ───────────────────────────────────────────────────────────────
   投资的逻辑 / investing track  (The Logic of Investing — How a
   thoughtful long-term OWNER of businesses actually thinks, distilled
   from the investing canon: Graham, Lynch, Buffett/Munger, Fisher,
   Marks, Malkiel/Bogle, Housel).

   The FOURTH sibling of the finance family. Its three siblings each
   sit in a different seat:
     · markets     — spectator, watching the whole machine
     · trader      — the risk/market-making seat, seconds-to-days
     · financials  — the analyst, reading the company's self-report
     · investing   — the long-term OWNER, decades, temperament > IQ  ← this

   Inherits financials' sheet verbatim (which @imports trader → cosmos →
   RL base), so it already has: kicker / source-note / takeaway /
   position-grid / coverage-grid / lesson-flow / mini-flow / trade-table /
   toc-grid / widget / kpi-grid / controls / prompt-list / dist-canvas /
   callout ok|warn|bad, plus trader's ledger / chip-row / chip / payoff-legend
   and financials' northstar / chip.flag / noise-row — all reusable here
   (northstar = "the one principle to remember", ledger = a mini owner-earnings
   statement, chip = a stock category).

   A few investing-only helpers below. They degrade gracefully — every
   widget still works with the standard .widget / .kpi-grid / .dist-canvas
   shells, so these are optional sugar.
