+## 2026-07-27 - Landing stylesheets made direction-aware (#146)
+
+- Trigger: looking back at #146 — the Persian reader whose right-to-left note content laid out left-to-right, fixed in v2.28.0 — the same question one level up: the app handles RTL, the site around it never had to. The work started as a Persian README plus landing page; the maintainer cut that mid-flight, leaving only the part that has to exist before any RTL page can.
+- Analysis: both stylesheets were written in physical directions — `left` on the skip link and the file-receipt card, `border-left` on the trust-ledger dividers, `padding-left` on the feature-point bullets and their `::before` dash, `margin-left` in the file-browser bar, `text-align: right` on the channel-row status, `padding-left` on the privacy page's lists. Each is a no-op to swap under LTR and a visible break under RTL. Three things do not follow from direction at all: the font stacks name Latin/CJK faces only, the display tracking is negative (which closes up a joined script), and `translateX` on the channel-row hover has no logical form.
+- Contract/scope: physical offsets become logical (`inset-inline-start`, `padding-inline-start`, `border-inline-start`, `text-align: start/end`); the three exceptions get `[dir="rtl"]` rules — an Arabic-script *system* stack (no webfont, the pages fetch nothing), `letter-spacing: normal`, and a mirrored hover nudge with its `:active` reset. No new page and no content change: the six landing pages, six privacy pages and six READMEs are untouched.
+- Verification: geometry diff of every element on 14 pages x 4 widths, old CSS vs new. The twelve real pages come out box-identical; the only computed-style change anywhere is `text-align` reporting `start` instead of `left` on three `.channel-row em`. Two throwaway `dir="rtl"` copies of `index.html` and `privacy.html` moved 20 elements and picked up the new stack, and screenshots confirm the mirror by eye — the file-receipt card and its accent border swap to the inline-start edge. `check-landing-overflow.mjs` passes 14 pages x 6 widths with both probes included. Pixel diffing was tried first and abandoned: the animated tablet GIFs and the `loading="lazy"` webps make the *same* tree screenshot differently twice, which read as four to nine phantom regressions per run.
+- Gate: `landing-check` only fired on `docs/**.html`, so a stylesheet change — the one most able to overflow a page — reached `main` untested. `docs/**.css` added to both path filters, which is what makes this change itself gated.

 ## 2026-07-25 - Notes grid, first-line titles, and v2.32.0 (#279, #280)
 
 - Trigger: two feature requests filed the same afternoon by one external reporter — a grid view for the notes list (#279), and a title field for each note (#280), the second reported as "what is set as the title is not necessarily the first line".
