feat: Reluctant Motivation subscribable calendar feed

Add a fun, on-brand ICS feed people can subscribe to: one all-day note
every 2-4 days with gentle encouragement, snark, and calendar-nerd jokes.

- gen-motivation-feed.js: deterministic generator, 605 notes across
  2026-2030 from a curated pool. Gaps 2-4 days, tones spread so no two
  adjacent notes share a kind; byte-identical on re-run.
- reluctant-motivation.ics: all-day VALUE=DATE events, TRANSP:TRANSPARENT
  so they never block the day, stable per-date UIDs, refresh hints.
- Landing page in the site design system (calendar-grid hero, marigold
  "today" highlight, agenda view on mobile), copy-URL + webcal/gcal buttons.
- SEO: FAQ schema, canonical + OG tags, branded social card, sitemap 0.7.

+# Reluctant Motivation feed
+
+A calendar feed people subscribe to for a little encouragement, a little snark,
+and the occasional calendar-nerd joke — one all-day note every 2–4 days. It
+means well, mostly.
+
+- **Feed:** `https://kashcal.onekash.org/reluctant-motivation.ics`
+- **Page:** `https://kashcal.onekash.org/reluctant-motivation`
+
+## Files
+
+| Path | Role |
+|------|------|
+| `scripts/gen-motivation-feed.js` | Generates the ICS. Deterministic — same inputs, byte-identical output. |
+| `static/reluctant-motivation.ics` | The committed feed (Docusaurus serves `static/` at the root). |
+| `src/pages/reluctant-motivation.tsx` | The subscribe landing page (calendar-grid hero, FAQ schema, copy button). |
+| `src/pages/reluctant-motivation.module.css` | Scoped styles, using the site's brand tokens. |
+| `static/img/social/reluctant-motivation.png` | Social share card (1200×630, brand teal). |
+
+## Regenerate the feed
+
+Run on demand — this is a committed source asset, not a build step (same as the
+social cards):
+
+```bash
+node scripts/gen-motivation-feed.js              # this year + 4 (5 years)
+node scripts/gen-motivation-feed.js --years 8    # a longer horizon
+node scripts/gen-motivation-feed.js --start 2027 --years 5
+```
+
+The build is reproducible: the gap between notes and the note chosen for each
+date are derived from a hash of `(year, date)`, and `DTSTAMP` is fixed per year
+(not "now"), so re-running produces an identical file. Tones are spread so no
+two adjacent notes share a kind and the largest kind doesn't clump at the tail.
+
+To add or change notes, edit the `QUOTES` array in `gen-motivation-feed.js`
+(each entry is `[kind, text]`, kind is `Gentle` / `Snark` / `Calendar joke` /
+`Sincere`) and regenerate. Keep summaries short — they show up in one day cell.
+When the feed nears its final year, re-run with a later `--start` and commit.
+
+## Feed shape
+
+Each note is an all-day event (`DTSTART;VALUE=DATE`), `TRANSP:TRANSPARENT` so it
+never blocks the subscriber's day, with a stable per-date `UID` and RFC 5545
+line folding. Calendar-level `REFRESH-INTERVAL` / `X-PUBLISHED-TTL` / `SOURCE`
+tell clients to re-fetch, so new notes appear on their own.
+
+## Social card
+
+Regenerate only if the title/tagline changes (needs `rsvg-convert`):
+
+```bash
+# see the inline SVG in git history, or re-run the one-off snippet used to
+# create static/img/social/reluctant-motivation.png
+```
