chore(memory): Basic Memory trial begins — sync normalization baseline (283 files)

Basic Memory v0.21.6 first sync over the live memory dir (steward-authorized
live-dir trial, Option A 2026-06-06): adds permalink: to frontmatter, refolds
long YAML description lines, strips final newlines. Bodies untouched —
verified via full diff classification. From this commit forward, any diff in
claude/memory shows only what Basic Memory or the session writes.

Trial design: MemPalace untouched as incumbent; git status check on this dir
at every wrap; end-of-day evaluation (recall quality, sync robustness,
rebuild-from-files, malformed-file behavior).

 ## Mode-mechanism modernization (decided 2026-05-30 — the thing the steward had been wanting to resolve)
 - Steward asked if the dark/light mechanism could be improved (he'd settled on "good enough"). Tracing it surfaced 3 seams (auto doesn't follow system on most pages — default.html inline sets auto→data-theme=''→light; FOUC risk; two divergent JS paths) + vestigial _dark.scss. His own font-size-percentage analogy became the governing PRINCIPLE: *honor the reader's environment, never ask them to re-declare what their system already knows* (type-size + motion already obey; colour was the lone imposition via the toggle). DECIDED: **drop the toggle, adopt the system** via `color-scheme: light dark` + `light-dark()` (pure CSS, zero JS, no FOUC) — even simpler than my light-dark()+toggle proposal. **+ P3 wide-gamut + prefers-contrast IN SCOPE** (steward "definitely want p3 ... and contrast"). The web preference matrix (contrast / P3 / inverted-colors / reduced-motion; ambient-light = unsupported gap) composes with light-dark(). Founds the vignette (most mode-coupled object; frontispiece divergence would bite it). Design note: `drafts/mode-mechanism-modernization-2026-05-30.md` (4e4f700). **Do-once consequence: the piecemeal dark→var MIGRATE is SHELVED** (light-dark deletes _dark + scattered blocks wholesale) — caught before investing in throwaway work. §I.h blockquote + token rename stand. Plan updated §5b. This is the kind of "the better way is also less code, and resolved before the dependent build" win the directive prizes.
