+# PLOTFLOW brand pack — 井筒に橘
+
+Colors: red #e8351f · olive #43463e · bristol #f6f3ec · ink #15160f
+
+## SVG (resolution-independent)
+- `plotflow-crest-stroked.svg` — primary mark. Stroked red; use on dark grounds.
+- `plotflow-crest-ink.svg` — flat ink form; use on paper/light grounds, print, seals.
+- `plotflow-tachibana-stroked.svg` / `-ink.svg` — plain 橘 (no frame), the
+  small-size form for 24–48 px display. Below 24 px use a text glyph.
+
+## PNG (socials, ready to upload)
+- `avatar-tachibana-1024.png` — **recommended avatar** (Instagram/Etsy/X).
+  Profile photos render tiny; plain 橘 stays legible where the framed
+  crest goes muddy.
+- `avatar-crest-1024.png` — full crest on olive, for contexts that show
+  the avatar large.
+- `banner-1500x500.png` — X/Twitter header (lockup, stroked on olive).
+- `banner-etsy-1600x400.png` — Etsy shop banner (flat ink on bristol).
+
+Site files (already wired): `/favicon.svg`, `/apple-touch-icon.png`,
+`/assets/og.png` (1200×630 share image).
+
+Rules (from the logo spec): the crest is the only red in a lockup; framed
+crest never below 48 px; no containers, gradients, or shadows; the
+literal * stays in running copy — the crest never replaces punctuation.
